Ignition Cap and Rotor Replacement Service and Cost

Common Symptoms

Ignition cap and rotor failure can be caused by failures elsewhere in the ignition system. The ignition wires and spark plugs should be thoroughly inspected. Old plugs or wires will burn out even a new cap and rotor.

Engine fluid leaks can cause damage to the ignition cap and rotor. These leaks should be repaired when the cap and rotor are replaced.

A failing ignition cap and rotor can cause hard starting, rough idling, and poor acceleration. It can also cause the Check Engine Light to illuminate. Continuing to drive with a bad cap and rotor can cause engine misfiring, which can ultimately damage the catalytic converter.

Best Practices

The ignition cap and rotor should always be replaced as a set.
