Prevent and Detect Problems

Regular tune-ups can help prevent problems, and catch problems earlier before they become big costly repairs.

Taking your car in for tune-ups can make the difference between expensive breakdowns and keeping your car running smoothly for years to come. While a tune-up isn’t a cure-all, it can help you and your mechanic stay on top of any potential problems before they cause permanent damage,

 

What Happens When I Take My Car in for a Tune-Up?

 

Performance Checks

  • Battery voltage – your batteries ability to charge and hold charge
  • Power balance – identifies mechanical problems like worn rings, bad head gasket, bad cams, and leaky exhaust valves
  • Engine vacuum – detects air leaks and exhaust restrictions
  • Faulty codes – verifies that no fault codes are present
  • Exhaust emissions – tests your car’s ability to meet emission standards
  • Idle speeds – checks how your vehicle idles and what mixture of fuel it is using while it idles
  • Ignition timing – detects possible sensor and computer problems related to your ignition

 

Replacements

While a tune-up could help you find any number of things that need replacement as needed, there are three main areas you should be focusing on.

Spark Plugs

Spark plugs need to be changed periodically as they wear down every time they fire. After about 45,000 miles your spark plugs have fired 60-80 million times and they have begun to erode. Instead of having sharp edges they will become rounded and dull and the distance between spark plugs will have increased, causing potential misfires.

Oxygen Sensors

Underperforming O2 sensors can cause a variety of problems with the drivability of your car. If your vehicle needs new O2 sensors it might not pass emissions. To prevent these problems your mechanic should check if your O2 sensors need to be replaced at your tune-up.

Filters

Fuel filters, air filters, PCV valve and breather filters should all be checked at your tune-up and replaced as needed.

 

Cleaning

While the need to clean your fuel injectors and intake system is not as important as it once was, it is still good to make sure they are cleaned if needed.

Fuel residue deposits on your injectors and this can restrict the amount of fuel delivered to your engine. This can result in misfire and deterioration of engine performance. This residue can also accumulate on the back of your intake valves causing hesitation problems with your engine. Cleaning is suggested if you are noticing performance issues or you have reached over 50,000 miles.

How Often Should You Get a Tune-Up?

Tune-up intervals vary between cars.

Newer cars that have electronic ignition and fuel injection systems have a much wider range – 25,000 to 100,000 miles. If you do a lot of stop and go driving or are regularly pulling heavy loads then you may need tune-ups more often.

You should always refer to your owner’s manual, or a trusted mechanic to determine your recommended tune-up intervals. It is in your best interest to adhere to these directions in order to keep your car working at its peak efficiency.
