A spark plug delivers the electrical spark that ignites the compressed air-fuel mixture in the combustion chamber, a job every gasoline engine repeats on every power stroke.
Signs a plug may need replacing include rough idle, misfires, hard starting, hesitation and reduced fuel economy. These symptoms can have other causes, so diagnose first; if a worn spark plug is the cause, this replaces it with a fresh ignition point.
