Q:
A: A good tune up consist of new spark plugs, new spark plug wires, maybe and air filter. Tune ups depend on what needs to be replaced or what is recommended in your owners manual at certain number of miles of the car. Some cars should have certain parts inspected and some recommend replacing parts such as drive belts and timing belts. I say the most your lancer needs being that it is a 2003 is just new plugs and wires and new air filter.
