If your car isn’t starting or running smoothly, faulty spark plugs could be the culprit. Understanding what they do and recognizing the signs of wear can help you avoid bigger problems down the road. Spark plugs receive an electrical signal from the ignition coil and use it to ignite the air-fuel mixture inside the engine’s cylinders at precise intervals. This controlled explosion is what powers your car's engine and keeps it running efficiently.
