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.
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.
