The most common sign that a spark plug needs replacing is an engine that hesitates during acceleration. Other warning signs may include engine misfires during startup, rough idling, sluggish acceleration, declining fuel economy, and engine knocking.

If you're considering having your vehicle's spark plugs replaced, there's a good chance the spark plug wires should be replaced as well. Ignition wires become brittle over time, and worn wires can lead to engine misfires, poor performance, and reduced fuel economy.

Come by Central Automotive Supply and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a routine 50,000- or 100,000-mile manufacturer maintenance service.

The short answer is no. The longer explanation is that the light may indicate a serious engine problem, and continuing to drive as if nothing is wrong could result in much more expensive repairs. A check engine light means you should have your vehicle inspected as soon as possible by a professional at Central Automotive Supply in Centralia.

A loose gas cap is one of the most common reasons a check engine light comes on. However, the best way to determine the exact cause is to have a technician at Central Automotive Supply read the diagnostic code stored in your vehicle's onboard OBD computer.
