NOTE:
THIS BULLETIN APPLIES TO VEHICLES WITH 2.5L V6 ENGINES
SYMPTOM/CONDITION:
Some vehicles may exhibit an intermittent sag or hesitation, engine miss or poor performance with no apparent Diagnostic Trouble Codes (DTC's). This condition may be related to the ignition pulse being out of sequence or low secondary ignition from the distributor ignition coil pack. This may be due to excess solder between the coil output terminal and coil cover plate.
DISCUSSION:
Using the Mopar Diagnostic System (MDS) or the Diagnostic Scan Tool (DRB III) with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If the above symptom has been experienced, the distributor should be looked at as a possible cause.
The distributors in question were manufactured prior to May 23, 1996. To identify suspect distributors, check the manufacturing tag affixed to the side of the distributor. If the distributors were manufactured prior to this date, the distributor should be a considered as a potential cause for the condition. If built after the suspect date, further investigation will be required.
