CONDITION SUMMARY

Situation: 

NOTE: This bulletin supersedes all previous versions; the Service Instructions have changed significantly and are therefore not highlighted.

The engine may exhibit a misfire, poor fuel economy, hard starting, and/or a rough idle condition. The engine Malfunction Indicator Lamp (MIL) may also be illuminated with misfire Diagnostic Trouble Codes (DTC) P0301 through P0308 and P0316, depending on the affected cylinder(s), stored in the Engine Control Module (ECM).

Cause:  This may be caused by incomplete combustion caused by poor fueling.

NOTE: The Service Instruction may only be completed if no other causes for the misfire are identified after following SDD and TOPIx advice.
NOTE: The Service Instruction may only be completed if Diagnostic Trouble Code (DTC) P0316 and one or more misfire DTCs (P0301-P0308) is stored. If any other DTC is stored, investigate the cause and carry out the appropriate repair as a separate claim.
