Engine Tune-Ups
Spark plugs, filters, and timing checks to keep your engine running smooth, starting every time, and performing the way it should
Schedule A Tune-Up
Small Parts That Make A Big Difference
A tune-up covers the parts of your engine most likely to affect starting, idle quality, and overall performance over time. We replace spark plugs, service fuel and air filters, check ignition timing, and adjust idle and performance settings so your engine runs the way it did the day it left the factory.
A neglected tune-up often shows up first as a rough idle, hard starting, or reduced fuel economy, small symptoms that are inexpensive to fix now and more expensive to ignore.
