How Do I Know If I Need New Spark Plugs in My Car?

Misfires, rough idling, incomplete combustion, low fuel economy, trouble starting, lack of acceleration, engine surging, and a check engine light are typical symptoms of a failing spark plug in the car. One way to tell if spark plugs need to be replaced is to visually inspect them for wear indicators like rounded electrodes, significant carbon accumulation, or oil fouling. It's important to heed the manufacturer's instructions regarding the intervals between 30,000 and 100,000 miles for spark plug replacement. If in doubt, a qualified mechanic ought to run a diagnostic.

Other Components

  1. Starters

    Starters start engines and are essential to vehicle starting systems. When the ignition key or start button is turned, the starter motor turns the engine's flywheel, starting combustion.

  2. Fuses

    Fuses safeguard vehicle electrical circuits from overcurrent, which can cause damage or fire.
