P0300 - RANDOM MISFIRE DETECTED

Description:  The powertrain control module (PCM) continuously monitors all cylinders for a misfire. The DTC indicates that multiple cylinders are misfiring or the PCM cannot identify which cylinder is misfiring.
Possible Causes: 
  • Fuel concern
  • Oil aeration
  • High pressure oil pump concern
  • Base engine
  • Fuel injectors
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.
