P030x - Cylinder x Misfire Detected Description: NOTE: x represents cylinder number 1 through 9.
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, poor fuel metering, poor compression, or any other cause. Possible Causes:

• Ignition system
• Fuel injectors
• Running out of fuel
• EVAP canister purge valve
• Fuel pressure
• Evaporative emission system
• EGR system
• Base engine

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.
