Repair Procedure
1.
Confirm if vehicle is currently misfiring, running rough or hesitating.
If YES - Go to Step 2.
If NO - Review Freeze Frame Data and attempt to operate vehicle under similar driving conditions - see notes below for information that makes it
more likely to duplicate misfire.
NOTE:
The following activities will turn off misfire detection:
^
Changing engine RPM greater than 150 RPM.
^
Changing throttle position quickly.
Misfire duplication can be duplicated most readily when the engine speed and throttle angle are held nearly constant for at least 2 minutes.
