P0301 - Cylinder 1 Misfire Detected

Description:  The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, incorrect fuel metering, incorrect compression, or any other cause.
Possible Causes: 
  • Ignition system
  • Fuel injectors
  • Running out of fuel
  • Fuel pressure
  • Base engine
  • Exhaust gas recirculation (EGR) valve stuck open
  • Blocked EGR passages
Diagnostic Aids:  The malfunction indicator lamp (MIL) blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded and caused the vehicle to fail an inspection and maintenance tailpipe test.
