# Service bulletin IB\-09\-J\-003

## NHTSA's summary

ISUZU/CHEVROLET/GMC: SEE DOCUMENT SEARCH BUTTON FOR OWNER LETTER. THE FOLLOWING TABLE CONTAINS MANY POSSIBLE CAUSES FOR THE FOLLOWING SYMPTOMS. HARD START/NO START; ROUGH, MISFIRE, UNSTABLE OR INCORRECT IDLE; SURGES, LACK OF POWER, HESITATION, LAG OR STUMBLE. WHILE SOME OF THESE SYMPTOMS MAY LEAD TO COMPONENT REPLACEMENT, THE REPLACEMENT SHOULD NOT BE CONSIDERED A COMPLETED REPAIR. THESE TYPES OF SYMPTOMS HAVE A HIGH PROBABILITY FOR A REPEAT REPAIR SINCE THE TRUE SOURCE OF THE FAILURE IS TYPICALLY FUEL CONTAMINATION. \*PE UPDATED 3/23/12. \*PE
