Hard starting, a rough idle, misfires or poorer fuel economy can mean a spark plug is worn, but those symptoms also come from ignition and fuel faults, so find the cause first. With the engine off and cool, a pulled plug with a worn-down electrode, heavy deposits or a cracked ceramic insulator is ready to change.

Sold as a Dodge Caravan spark plug, it also fits the 1984-1987 Caravan 4-cylinder 2.6L, which takes four, and the 1987-2000 Caravan V6 3.0L.
