Tune-Up

Older cars that do not have fuel injection or electronic ignition typically get a tune-up every 10,000 to 12,000 miles. If you are on a 3,000 mile oil change schedule, then your tune-up should be about every 3rd oil change. 

Most newer vehicles have factory recommendations for tune-up ranging from 25,000 up to 100,000 miles. These vehicles will have electronic ignition and fuel injection. These vehicles will run more efficiently leaving less carbon deposits in the engine and on the spark plugs. 

A spark plug is a device that is attached to the engine and provides an electrical arc within the combustion chamber to ignite the fuel. Being inside the combustion chamber, the spark plug is exposed to carbon. Carbon is a byproduct of combustion and carbon build-up is the primary failure of spark plugs. Spark plugs are replaced during every tune-up.

Plug wires carry the electric current to the plugs. If they are damaged or worn, the plugs will operate inefficiently, causing misfire and loss of power. Older cars using plug wires should have them changed with their plugs on about the 3rd tune-up.

 A coil pack is a part of the ignition system. The electronically-controlled pack consists of ignition coils that are controlled by the car's computer. The main job of the coil pack is to increase the electricity needed, and then release it through the spark plug wires. Coil packs are designed for longevity. Generally, these don't have to be replaced until about 100,000 miles. If one fails, you should get an engine light you can have coded and it will tell you which coil is bad.

 As the tune-up needs are different for almost all vehicles, cost and time will be very specific to your vehicle. Please call the shop for an estimate and to schedule your next tune-up! 423 305 1133
