Car Tune Up Checklist And Benefits

Car Tune Up Checklist And Benefits

Your car will need regular checks to ensure it performs as expected on the road. Performing regular car tune-ups will significant boost the performance of your vehicle and increase your gas mileage.

What happens during a car tune-up has changed significantly over the years as automotive technology has advanced and legislation has come into effect. You need to ensure certain tasks are carried out to be confident your vehicle is safe; but, the definition of a car tune-up is not the same everywhere.

So here is the car tune up checklist and what you can expect from you visit at RPM Auto Repair.

Car Tune Up Checklist at RPM Auto Repair

The first thing we do is a number of checks to see where problems may be. Our car tune-up checks include:

  • Scan for faulty codes
  • Battery voltage
  • Tire pressure test
  • Inspect spark plug wires, distributor cap and rotor
  • Replace spark plugs
  • Check and adjust curb idle speed as required
  • Clean fuel injectors
  • Visual check of emission control related devices
  • Exhaust emissions (this is a must to ensure your vehicle meets legal requirements)
  • Verify idle speed
  • Check and adjust ignition timing as required
  • Hoses and belts for wear and tear
  • Check all fluid levels
  • Road test vehicle

About Repairs And Replacements

Next to the items on the car tune up checklist, you might want to consider replacing some parts depending on your mileage. These include the spark plugs, rotor cap, distributor cap, fuel and air filters, PCV valve, sensors and breather filter.

The spark plugs need to be changed periodically for safety. The electrodes wear every time the plugs fire; by the time that vehicle has travelled 45,000 miles the spark plugs would have fired approximately 60-80 million times. The wear on the spark plugs can cause the sharp edges to become smooth and rounded and the distance between the plugs is greater. This therefore requires more voltage for the ignition or the plug may misfire.

You should also ensure your O2 sensor is replaced periodically. EPA studies have found 70% of vehicles failing their emissions tests require a new oxygen sensor. A slightly worn O2 sensor will cause your vehicle to use more fuel. In theory, you should get a Check Engine or Malfunction Indicator Lamp warning when the O2 sensor begins to degrade; but there are many cases when a badly worn one will still function without the warning.
