What Do Spark Plugs Do?

Spark plugs are a vital part of your car’s normal operating system. Spark Plugs is an appropriate name because electricity or sparks travel between the two small leads at the end of the plug. Consequently, when your car is running, a spark plug is constantly supplying a spark that ignites an air/fuel mixture within a given cylinder of your car. When the air/fuel mixture ignites, it results in an explosion that allows your engine to produce power.

Spark Plugs Failure Symptoms

Dirt, oil, or carbon buildup can lead to premature spark plug failure. If you have bad or failing spark plugs your car will likely be running poorly. Your vehicle may exhibit common symptoms such as rough idling, engine misfires, hard starts, lack of acceleration, and reduced gas mileage. Bad spark plugs may also trigger the check engine light.
