Symptoms of Damaged Spark Plugs

Sterling McCall GMC invites you to discover what the symptoms of damaged spark plugs are.

The most obvious symptom of faulty spark plugs is your vehicle just seems a little ‘off.’ It would probably start slowly with something as simple as lower fuel efficiency but could progress to no acceleration. Faulty spark plugs or spark plug misfires can also cause problems starting the engine, a rough idle once started, and even low power. What might start as only a minor inconvenience could end up being a safety hazard. Regardless if you are already having issues or want to replace them before they happen, let us take care of it. Our highly-trained technicians will check out your vehicle and provide you with options for the best course of action to keep your vehicle on the road.


What Do Spark Plugs Do?

Spark Plugs, What Do They Do?

A spark plug is a part of the normal gasoline engine that delivers a small spark of electricity to ignite the fuel. Without spark plugs, an engine cannot run or start. To ensure the engine runs at its best, we use the correct spark plug gap. A gapping tool is used to make an exact measurement (between .020 and .040 of an inch) to make sure the spark plug gap is correct. This is only applicable to gasoline engines because diesel engines don’t use spark plugs. In place of spark plugs, diesel engines have a separate system that has glow plugs.

Benefits of Changing Spark Plugs

The biggest benefit of changing your spark plugs is the vehicle should run better, give better gas mileage, and could reduce the pollution from the vehicle. The price to change your spark plugs is reasonable, as well. While everyone has a thought on the best spark plugs, we use the spark plugs that the manufacturer originally installed. So, bring your car in and replace those dirty spark plugs and see how much you have been missing.

How Long Do Spark Plugs Last?

How Soon Should You Replace Spark Plugs On My Vehicle?

How Often Should I Replace The Spark Plugs On A Vehicle, well it’s complicated. Like many consumer products, there will be plugs that may only last about a year or plugs that may remain functional for several years. While it depends on your driving behavior, your car will have a unique replacement plan for the spark plugs. So, if your car is showing symptoms of fouled spark plugs, you can bring it to us for a complete check-up. Our qualified automotive technicians will check the plugs, wires, and coils for damage or even misfires during normal operation and get you out on the road ASAP.
