Spark Plugs
The spark plugs in your engine are located at the very top of the cylinders and ignite the mixture of air and fuel in the engine to power it. There will be one spark plug for every cylinder in the engine. Spark plugs are vital to keeping the engine going and should be checked regularly. Signs that your sparks may be malfunctioning include engine misfiring, slow acceleration, and weakened fuel economy.
