Tune ups use to consist of replacing the points and condensor plugs, distributor cap, air filter and fuel filter. But with the modern electronic Tune up, that has all changed. A modern tune up first hooks your car to our electronic scan and looks for maintenance codes. We also look at the manufacturers recommended maintenance guide that describes all changes required based on the age and mileage of your car. You can get expert Murrieta tune ups at Diversified Auto.
