Common symptoms of a worn distributor cap include engine misfires, poor acceleration, rough idle, difficulty starting, check engine light illumination, and diagnostic trouble codes such as P0300 (random misfire) or P0301-P0308 (cylinder-specific misfires). Bosch recommends replacing the distributor cap every 30,000 to 50,000 miles as part of routine maintenance. When replacing the distributor cap, it's recommended to also replace the distributor rotor for optimal ignition system performance.
