Signs of Bad Fuel Injectors

Is It Time for New Fuel Injectors?

A fuel injector is part of your vehicle’s fuel system. Fuel injectors are the component that spray the fuel into the engine. These are controlled by the vehicle’s engine computer (ECM), which controls how it sprays fuel into the engine, following purposely timed intervals and patterns that help optimize the engine’s efficiency and overall performance.image of used, dirty, fuel injectors.

Symptoms of a Bad or Failing Fuel Injector

There are many things to look for to determine if your fuel injector is failing in some way or needs to be replaced. Since these are a part of the fuel system, it’s important to watch for these symptoms to determine if the fuel injector is bad or failing.

Engine Performance Issues

Often, when a fuel injector is clogged or starting to fail, you will experience engine performance issues. These types of issues can include everything from engine performance issues to strange smells – all of which your local Minnesota AAMCO auto repair center can diagnose.

Check Engine Light Comes On

A bad fuel injector can cause too much or not enough fuel to be delivered into the engine – this will cause the Check Engine light on the car to turn on, indicating an issue. Your trusted Minnesota AAMCO auto repair center can help decipher your check engine light and figure out what issues need to be addressed.

Vehicle Won’t Start or Struggles When Starting

If the fuel injector is not delivering enough fuel to the engine system, this can cause the car to struggle when trying to turn over or not turn over at all (just cranks with no result). This can also cause the engine to stall due to the air-fuel ratio not being correct.

Vehicle Misfires

This can occur if your engine is not receiving enough fuel from the fuel injector – which stems from fuel injectors being clogged and dirty.

Poor Idle

You will notice a rough or choppy engine idle when the car is not moving. It might even feel like the engine it going to stall every time you stop. This can be caused by the fuel not being properly injected to the engine cylinder.

Engine doesn’t Reach Its Full RPM

If too much fuel is being injected into the engine, this can cause the engine to surge. This will make it feel like your car is jumping forward quickly but struggling to fully take off. You may also notice a loss in power or acceleration. 

Smell of Fuel

Another symptom of a failing or leaking fuel injector is a fuel odor. Because fuel injectors hold high amounts of pressure, and over time they can begin to leak around the seal at the tip of the injector or nozzle. A leak from either of these areas can affect engine performance – most noticeably fuel efficiency – and will give off the smell of gasoline. If you begin to smell gas fumes, you should take your car into a mechanic as soon as possible to avoid any further damage or safety hazards.

If you start noticing any of the previously mentioned symptoms, or suspect that there could be some issues with your fuel injectors or any part of the fuel system, schedule an appointment with a professional mechanic to diagnose the problem and provide next steps for how to fix it.

Tips for Affordable Car Maintenance

Save Money & Time With These Easy Tips

Maintaining your car so it is safe and reliable doesn’t have to cost a lot of money.

image of car speeding around bend on country road with sun shining through trees.

Having a car can be fun, and it definitely makes life easier, but when it starts to malfunction or break down, it can be a costly hassle and a safety issue. Your car can cost a lot of money if you don’t run a regular maintenance schedule. Making sure that maintenance is affordable and easy is important in our go-go-go world. Luckily, there are some things you can do to ensure your car is running smoothly and safely, without breaking the bank. Here are some handy tips and information on some simple, affordable things you can do to help your car run better and last longer. Grab a coupon and save some money with these local Minnesota AAMCO specials.

Get to know your car – read the owner’s manual.

Read and pay attention to the owner’s manual for your car. Don’t have one? Check with your local dealership or go online – there might be a PDF version you can grab, load to your phone and have with you at all times. No matter what car you drive, the regular maintenance schedule should be spelled out in the manual. Old myths like “Change your oil every 3,000 miles,” will go right out the driver’s side window. Of course, if the manual says you should change the oil every 3,000 miles, then do it – but we bet it doesn’t say that.

You’ll discover how often your manufacturer recommends to change the oil for best performance and reliability, as well as even what kind of oil to use. Your owner’s manual will also enlighten you on many other aspects of your car and the things that should be regularly maintained – such as the all-important transmission fluid, filters, timing belts, hoses, battery, lights, and fuel types. All of this information is available in the car’s owner’s manual.

If you’re part of the TLDR crowd, then just consider this: you’re throwing away good money by not taking care of your car, and to do things right you have to educate yourself. Most car owners know how important it is to know at least a little about their cars, but even if you’re not interested in how your car works you should know a little about it, otherwise you run the risk of being taken for a ride with some shady mechanic (more on that later). Knowing some simple things, like the right kind of oil to use, for example, can save you trouble in the long run. Even knowing what kind of fuel is best for your car is really important and can save you a lot of headaches – and money – if you just know. Doing the wrong thing or treating your car poorly might run the risk of voiding your warranty or even worse – causing damage that requires expensive repairs.

Sure, these days we can just pick up our smart phones and holler questions at it and get quick answers. Good, solid answers that provide you useful information that helps you make good decisions can be hard to come by, though – even in this day of information access (and overload). If you want to know more about your car or are concerned about its performance, or why it’s making weird noises. why your ride is bumpy even on smooth roads, or if you know you need repairs, call your local Minnesota AAMCO auto maintenance and repair center.

Check and Change Your Oil

Old story, been handed down from campfire to Facebook – but oil is vital to the successful operation and long life of your car’s engine. Checking the oil is a good habit to get into. Even if you think everything is fine, it’s a good idea to check it when you stop to get gas. It’s easier than it sounds. Pop the hood (you do know where the hood release lever in your car is, right?), grab some paper towels (usually found with the windshield squeegee around the gas pump), pull the dipstick, wipe it, put it back in, pull it back out, and see where the oil meets the fill line. If it doesn’t meet the fill line, it’s low. Repeat the steps and check again, but if it’s still low you should take your car in for a checkup to find any potential leaks or areas that might be eating or burning oil.image-hand-of-mechanic-holding-white-rag-with-oil-dipstick

Also pay attention to the color of the oil. It should be golden and clear. If it’s dark brown, a change is in the near future. If it’s black and/or thick and gooey, it should be changed as soon possible – don’t wait! Modern cars will tell you with an electronic warning light when it’s time for that regularly scheduled oil change you read about in the owner’s manual. Keep in mind that checking the oil after the car has been running might not give you the most accurate read on level. You’ll want to double check once the car has had a chance to cool down and sit a while. This gives the oil a chance to recollect in the oil reservoir, which will give you a more accurate read on its level – and you can get a better read on the color, too.

Go beyond oil and learn how to check other important fluids in your car.

Even if you don’t know how to change your antifreeze, power steering, transmission, or even your wiper fluid, you should learn how to check them and which ones to top off, which ones to have changed by a mechanic. Wiper fluid – don’t let someone charge you for this, unless it’s part of a larger package deal. That is so simple, it’s painful to think of paying to have it done.

For many fluids you can see the tank level directly, but most have gauges or dipsticks that help you check the levels. Even if your owner’s manual doesn’t provide much information or guidance about checking things such as your transmission fluid or coolant, don’t be afraid to educate yourself. Go online and find answers, or just open the hood and look around. See if you can find the right tank, cap, or dipstick (they’re usually labeled to some extent). If you’re running low, add more fi you can, or schedule a maintenance appointment with your trusted mechanic. If you notice a leak of some sort, definitely take your car in for diagnosis and repair.

Check the battery and make sure it’s clean and good to go.

Check the battery for signs of corrosion, and generally keep it clean and clear of debris. Make sure any terminal convers are secure and clean, and clean the terminals if necessary. Most batteries these days don’t require much manual maintenance, but you should know where the batter is and check it from time to time, usually along with the oil. This will help you ensure it’s not leaking and there is no corrosion or crud building up on the contacts. If there is, clean them with a battery cleaning brush. The brush doesn’t cost much and it’s a quick, easy thing to do. Also consider getting a simple battery tester or jump starter. Using these, you can monitor your battery and know when it needs to be replaced before it leaves you stranded. You’ll never have to call or wait for roadside assistance.

Get your timing and serpentine belts replaced when necessary.

image of engine with serpentine belt

The engine timing belt is usually replaced every 60,000 miles or so, and the serpentine belt about every 40,000 miles. Again, your owner’s manual is the authority on this. These are really important parts that can make or break the engine. If you don’t have the owner’s manual, look online to get this important information, or call your local Minnesota AAMCO. If you’re just not sure, or know that it’s been a long time (or never) since you last even thought about that serpent timey belt or whatever it’s called, schedule an appointment and ask your mechanic to inspect all belts and hoses and replace them if necessary. You just don’t want to let them fail. It is not only a matter of having a safe and reliable car, but if you wait and those belts do fail, your car will break down, possibly leave you stranded or in an unsafe place – and leave you with costly towing (if your mechanic doesn’t do it for free within a certain mile radius). It can also damage other engine parts and systems, making repairs even more expensive.

Rotate and balance your tires, check the alignment.

Tire rotation and balancing is often overlooked by drivers. It does take time, you always have to battle a long line, and it’s just never convenient (when is any car-related maintenance or repair convenient?). Once again, your trusty owner’s manual will tell you how often to rotate the tires. It’s important to make sure your tires wear evenly and your car drives smoothly, not only because your fuel efficiency is directly affected by these factors, but your safety is, too. The saying that you’ve got a lot riding on your tires is true! You can make your tires last a lot longer by having them rotated and balanced. Along with that, your alignment is just as important. If you’re fighting to keep your car driving straight or having trouble safely navigating curves and turns, it’s time for an alignment. Alignment also affects the wear of your tires. Bad alignment will cause serious wear and tear on your tires, risking flats and, even worse, blow outs which can be dangerous or deadly high speed.

Change the spark plugs.

If the spark plugs are worn out or covered in crud, your engine is not running efficiently. This alone can cost you a lot of money in fuel, and it can lead to a breakdown. This might be a little more technical than you’re comfortable with, but in many cases checking and replacing the spark plugs is not that difficult. If it’s something you just don’t want to do – especially if it’s complicated for your vehicle, just follow the recommendation in the owner’s guide. Take your car to your trusted mechanic and get those spark plugs changed on time – usually around 30,000 miles for standard copper spark plugs, but it can vary.

Find a Reputable Repair Shop with Certified Mechanics

Finding a mechanic you trust is important, and sometimes not easy. It can take time, and might involve some trial and error, as well as, unfortunately, some money in the process. If you’re lucky, you’ll find a mechanic who is honest, trustworthy, tells you like it is, and doesn’t do any repair work that is unnecessary – and definitely not until you give the OK.image of smiling AAMCO mechanic tipping his hat.

Some Causes of Smells Coming From Your Car

5 Things Your Nose Can Tell You About Your Car

Besides that new car smell, there are fairly few odors you experience in or around your car that are pleasant. Your nose knows when something is foul or amiss. Some smells are pretty telltale of a certain condition, while others might present a little more mystery in need of investigation. Here are five odors that are indicators of potential problems with your car.

Hot or Burned Oil

The smell of hot or burned motor oil could mean that a gasket or seal is failing. This lets engine oil leak onto hot engine parts. Additionally, a leaky transmission seal can cause oil to spray all over the engine, including the manifold. These hot engine parts burn off the oil, creating bluish white smoke that wafts from under the hood.

The first thing you should do is check the oil to make sure it is at the correct level and that it’s clean. Small leaks often become bigger leaks, so check under the car, on the pavement where you park, and around the engine for signs of leaks. If your car is running low on oil, the engine can overheat and burn whatever oil is remaining.

If the burned oil smell is coming from the tailpipe (bluish white smoke), it is a symptom of oil leaking into the combustion chamber, which means it is getting into your exhaust system. The oil is burned in the combustion process with the air and fuel mixture, and pushed out through the exhaust system. The exhaust system is one of the hottest systems in your car, dealing with the noxious byproducts and fumes of the internal combustion engine banging away under the hood. If oil leaks into the either the combustion or exhaust system, it is going to be burned. This is usually a sign of an old, worn out engine in need of some serious repair and regular maintenance.

GasolineAAMCO Minnesota Vehicle Bad Smells

If you smell gasoline, like when it’s pumped at the gas station, inside or outside the car, you should take special care to identify the source. It is likely a sign of a gas leak in the fuel line or fuel injection system (if your car has one). A leak in the fuel tank vent hose oftentimes is the culprit behind gasoline odors inside the car, especially after filling the gas tank. At worst, there could be a leak in the gas tank itself.

In older pre-1980’s cars, the smell of gasoline can occur after the car has been turned off due to fuel afterboil. This is often normal and results when a small amount of gasoline continues to burn in the carburetor after the engine is shut down.

Any persistent smell of gasoline, either in the car or outside of the car such as in the garage, should be taken seriously. Any smell of gas fumes can indicate a fire hazard, so it should be checked immediately.

SyrupAAMCO Minnesota Bad Smelling Car

If you detect the scent of maple syrup, it probably means there is a leak in the cooling system. Cooling fluid is leaking onto hot engine parts and being burned away. If there is a leak in the cooling system, you need to check the coolant fluid level, check for leaks in the engine compartment and on the pavement in the areas you park (such as driveway or garage). Left unchecked and repaired, you will risk overheating the engine and causing major damage.

A syrup smell could also mean the engine coolant is boiling after you have turned off the engine. This is due to the inability of the cooling system to dissipate engine heat, so the engine remains extremely hot for an extended time even after it has stopped. If you decide to investigate, wait until the engine has cooled off! Never remove the radiator cap while the engine is running or is still hot. It will cause a massive blow off of superheated fluid that could cause serious injury.

Rotten Eggs or Sulfur

This wonderful stench means your car is in need of a checkup and that the catalytic converter is having some serious issues. The catalytic converter is in the car’s exhaust system and is supposed to convert noxious hydrogen sulfide to sulfur dioxide in the exhaust fumes before they exit the tailpipe. If this is not happening, it means that your engine needs more than just a tune-up, and the catalytic converter could completely overheat and fail, leading to costly repairs.

Burned PaperBad Smelling Exhaust Fumes

If you smell something like burned paper, it could meant that your clutch is overheating. If you’re riding the clutch pedal, it creates excess friction between the clutch facing and slips. The material between these surfaces is made of a paper compound, which gives it its familiar smell.

The smell of burning paper could also mean your brakes are overheating. Riding your brakes, such as when coming down a hill or mountain, creates unnecessary friction and excess heat on your brake pads. You might also have a seized up brake piston, resulting in a “dragging brake.” Or it could be that you just left your parking brake on. In some cars it is easy to forget and actually drive with the handbrake still engaged.

 

AAMCO Minnesota Can Help Sniff Out and Fix Problems With Your Car

We realize that in order for one to understand some of this, you must know what the “smells like” really smells like. If you’ve never had maple syrup – get thee to a pancake house now – you’ll likely not know what to sniff for. Whatever the smell, if it’s not new car or the scent of that air freshener you just bought to battle the gym socks and mildew in your car’s air filtration and circulation system, then you should come to AAMCO Minnesota for a multi-point diagnostic inspection.

Visit an AAMCO Minnesota transmission repair and total car care center near you. When issues arise and you need affordable, honest auto repair, schedule an appointment with your locally owned and operated AAMCO Minnesota transmission and auto repair center.

If you have questions about your car’s road readiness, or about car repair and maintenance topics, AAMCO Minnesota is a great resource for expert automotive repair and maintenance information. Feel free to call or visit your local AAMCO Minnesota transmission and total car care center.

Reasons Your Ride is Bumpy and Rough

Signs Your Battery Needs to Be Replaced

Slow Engine Crank

It takes a lot of power to get your car started, and all that power is produced by the battery. Once the car is started, the alternator keeps the car battery going by replacing the power used to start the engine and run your vehicle’s electronic accessories. When you put the key in your car’s ignition and turn it, the battery alone starts the engine. If the battery is weakening, you may notice that the engine turns over slower than usual. It’s important that you pick up on that warning sign, you may be stranded if it takes more than one crank to get the engine to fire. If the engine does not crank at all, the vehicle will often just make a rapid clicking sound, this indicates that the available power is too low to crank the engine. Bring the battery in and have it check at your Local AAMCO.

Issues with electrical components

In addition to powering the engine, the car battery also needs to produce enough power to operate the other electrical components in your vehicle. Modern cars have many electronic accessories including power windows, power seats, radio, windshield wipers, dashboard lights, headlights and more. All of which require electricity supplied from your vehicle’s battery.

If you start to notice that your electronic components are not operating like they used to, this may be a sign that the battery is wearing out. You may want to check for power loss due to dirty battery terminals. If it appears clean, it might be time for a battery replacement. Pay special attention to when you use more than one component at a time. For example, if you switch on the radio while using the headlights and the headlights go dim, the battery might not be as young as it once was.

Dashboard Warning Light

Most cars have a dashboard warning light, usually in the shape of a battery. This will illuminate if the battery is not being replenished properly or if there is an internal problem with the battery. Like the Check Engine light, the battery warning light might also mean that something is wrong with the alternator or some other part of the electrical system. If the light comes on, the best course of action would be to have your vehicle’s electrical system inspected by your local AAMCO.

Swollen Battery Case

When a car battery is exposed to excessive amounts of heat or cold, the flat sides of the battery case may swell or bulge. If for example the battery sits in a vehicle that is not driven for some time in the winter, the battery may freeze. Freezing and swelling from excess heat often results in an electrically “dead” battery that cannot be recovered and will require replacement.

Old Age

On average, a car battery lasts about five years. This average lifespan will fluctuate depending on extreme temperature exposure, number of deep discharges and whether it goes through full charge cycles. That being said, five years is how much life most batteries have so once you hit the 4-year mark, it might not be a bad idea to get it tested by your local AAMCO to see how much life it has left. If you are not sure how old the battery is, you should be able to find the manufacture date on the battery case.Jumper cables and car battery.

Weird Smell

When a battery has been frozen, overcharged or is shorted internally its case may vent gas. If you happen to detect a rotten egg scent under the hood of your vehicle, have your battery inspected as soon as possible because in addition to possibly needing a replacement battery, the sulfuric acid can eat away at other engine parts, causing corrosion, which is something you want to avoid at all costs.

 

If you are experiencing any of these signs, schedule an appointment with your local AAMCO

Don’t Get Stranded by a Dead Battery

Car Won’t Start?
Battery, Alternator, or Starter – Which is the Problem?

If you have ever owned a car, there is a good chance that at some point you’ve experienced a dead battery. It almost always happens at an inconvenient time, with virtually no one you know anywhere nearby, during the week you cleaned out your trunk and removed the jumper cables… It is an awful feeling. But could it be your alternator, or starter, and not your battery?

Discovering Why Your Car Won’t Start

Check the Battery

When your car isn’t starting, it makes the most sense to start by checking your battery. An average car battery typically lasts 4-5 years, but may be shorter in warmer extreme climates. In cold weather, it is relatively common to find your battery has died, see our blog article about Winter Battery Tips.

You can check the battery gauge on the dashboard of your vehicle to determine if the battery is sending a charge, even if the car is turned off. If there is a dim, flickering light, it means something is drawing power. Check your commonly used connections to see if they’ve been accidentally left on, like the automatic window, wipers, or lights (dome and head lights should be checked).  Once these connections have been shut off, try the battery once again.image - applying jumper cables to battery

Sometimes, your vehicle may require a jump. If you can jump your car and get it running but then it dies again when you shut it off, this is a sign that your battery is the problem. When checking over the health of your battery, you should be sure to look at the battery cables. These can get worn and damaged over time and may be contributing to the battery problems you’ve been experiencing. Typically, a car battery will be located under the hood, toward the front of the car on either the driver or passenger side, though so vehicle models store the battery in the trunk of the vehicle. Consult your manual for the exact location.

If you have a voltmeter (a device used to measure electrical differences between two points in an electrical circuit) you can check the integrity of the battery. If it reads between 14-15 volts, then the battery is normal. If the voltmeter reads over 15 volts or less than 13 volts, then there may be a problem with the voltage regulator, the wiring, or the alternator.

Check the Alternator

A dead battery can be one of the first signs of something being wrong with the alternator. If the battery is working properly and has no damage, then the issue is more than likely with the alternator. There are a couple of simple tests you can perform to check the alternator.image - car alternator

Turn your car on and let it run, unplug the positive connection from the battery, if the car stops, then your alternator is not working properly. The positive connection from the battery is red, while the negative connection is black. (Note: DO NOT attempt to test the alternator by unplugging the negative battery cable while the car is running. This can cause damage to your vehicle’s electrical system.)

Another way to check is by monitoring the dashboard lights. If the lights come on, but then slowly start to fade, this also indicates an alternator issue. There are a few signs to be on the lookout for should you suspect that your alternator is failing:

  • You will hear a growling sound before it goes out.
  • You may smell burning rubber or hot wires coming from your alternator overheating.
  • Your headlights (dash lights, dome lights, etc.) flicker, get dimmer, or are especially bright.

Check the Starter

Your starter has arguably one of the most important jobs to do. The battery sends a burst of electricity which the starter uses to turn the engine over and start! If you turn the key, but you’re only hearing a click, there is a chance that your starter is not working properly. A starter that is failing may crank the engine slowly, or may not crank at all. This sound is very similar to the sound the car makes when the battery is dead, so make certain to confirm the battery health first.image - starter

If you have ever had a starter go out on you before, and you’re familiar with the old “hit it with a hammer” trick to loosen the solenoid to get the motor started, this may well work to get you on your way. We’d like to discourage you from opting for the hammer to the starter method, and encourage you to schedule an appointment at one of our AAMCO Minnesota locations for a FREE multi-point courtesy vehicle inspection.

Figuring out why your car is not working can be an extremely frustrating and isolating feeling. At AAMCO Minnesota, we want to help you diagnose and fix the issues you are concerned about to help get you and your vehicle safely back on the road.
