What does a distributor cap do?
It covers the distributor and routes the ignition coil's high-voltage output through its terminals to each spark-plug wire, working with the rotor to send spark to the correct cylinder.
How do I know if my distributor cap is failing?

Should I replace the rotor at the same time?
