Engine Tune Up Services

A tune up replaces faulty components, and uses computerized diagnostic equipment to evaluate vital electronic engine components, like oxygen sensors and the control module.

The word "tune-up" actually applies only to older cars, on which you can perform the traditional work associated with the term-spark plug replacement, ignition contact point replacement, dwell adjustment, ignition timing adjustment and carburetor idle and mixture adjustment.

For most of today's cars, “engine performance maintenance” is a more accurate term. All modern cars and light trucks are equipped with electronic ignition and at least one on-board computer that automatically adjusts items like the ignition timing, fuel mixture and idle speed. In fact, on modern computer-controlled cars, it's impossible to adjust these yourself without proper education and training.

On an electronic ignition system, the basic tune-up procedures are as follows:

Remove spark plugs.
Replace spark plugs and gap spark plugs to manufacturer’s specifications and install in engine.
If applicable, check the distributor cap and rotor for cracks and wear. Replace if necessary.
Use tachometer to set idle speed to specifications (if adjustable).
Use timing light to set initial timing (most electronic ignition systems do not require adjustments).

An automotive tune-up is an orderly process of inspection, diagnosis, testing, and adjustment that is periodically necessary to maintain peak engine performance or restore the engine to original operating efficiency.
