P0300 - RANDOM MISFIRE DETECTED

Possible Causes: 
  • Fuel concern
  • Damaged high pressure fuel injection pump
  • Base engine
  • Damaged fuel injector
Diagnostic Aids:  Access the PCM and record the freeze frame data. The misfire freeze frame data may be used to determine the operating conditions when the misfire DTC was set.
