ENGINE TUNE UP
If something goes wrong with your vehicle’s engine, it’s best to get it checked out right away. Minor engine problems that go unattended can result in more costly repairs down the road. The term “engine tune up” is derived from the practice of tuning an engine’s ignition timing. The term, however, has survived to refer to a single preventative maintenance service that covers multiple checks to your engine’s components.
