Tune-up

The intent of a tune-up is to obtain the maximum performance and economy of the engine with the lowest possible exhaust emissions so that the vehicle engine will meet the manufacturer's specifications. It involves checking the components of the ignition system and cleaning or replacing them; cleaning and adjusting the carburation or fuel injection system; adjusting the points and timing cleaning and gapping the spark plugs. Tune-ups should be performed according to the recommendation of each manufacturer.
