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 when the
engine is either cold or hot. The engine Malfunction Indicator Lamp (MIL) may also be illuminated with misfire
Diagnostic Trouble Codes (DTC) P0301 through P0308, depending on the affected cylinder(s), and P0316 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.
Action: Should a customer express this concern, follow the appropriate Service Instruction (1, 2, and/or 3)
outlined below:

2. Read and clear all DTCs.
3. Start and run the engine until normal operating temperature is achieved.
4. Switch the engine 'OFF' and let stand for a minimum of six (6) hours.

continue to Service Instruction 3.
1.
NOTE: A printed copy of the Freeze frame data, indicating engine coolant temperature at the
time of the engine misfire, must be kept in the vehicle record file.
View the Freeze frame data for Diagnostic Trouble Code (DTC) P0316 or one misfire DTC (P0301-P0308) and
read the engine coolant temperature.

 If the engine coolant temperature is 76ºC or higher ('hot' engine), continue to step 2.

 If the engine coolant temperature is 75ºC or lower ('cold' engine), continue to Service Instruction 3 below;
do not replace fuel injectors.
2. If Diagnostic Trouble Code (DTC) P0316 and one or more misfire DTCs (P0301-P0308) is stored and no other
