A Car Tune-Up Service can Prevent Costly Repair
A Tune-Up is also known as a Major Service. It is a regular mileage based service performed on a car. A Tune-Up is usually performed at certain mileage intervals. The service intervals commonly occur at 30k, 60k, and 90k miles. As with all preventative maintenance performed on a car, a regularly scheduled Tune-Up service can prevent a myriad of costly performance problems. Depending on the mileage and age of the modern car, a tune up can vary in scope from a basic oil change to multiple fluid and filter replacements. Additional tune up services may include spark plug replacement, servicing of certain emissions items, and a deep scan of all vehicle computer systems.
On older cars, a tune-up may have included complete servicing of the ignition system. Replaced items include spark plugs, replacing ignition wires, ignition cap, and ignition rotor. The Ignition Timing of the vehicle engine would also need to be adjusted.
Modern cars have different tune-up requirements based on newer technology. Ignition Timing is computer controlled and no longer needs adjustment. Fuel filters are generally no longer serviceable. Multiple individual direct ignition coils, known as COP (coil-on-plug), have replaced ignition wires, cap, and rotors. COP units generally fail between 80,000 and 100,000 miles or 6 years. During a tune-up, it is best to replace all COP units.
