was wondering if anyone reading this group may be able to help. I have a
97 jeep grand cherokee limited, 6 cyl. have an intermittent problem: engine stalls and sometimes can be very difficult to restart. can happen before reaching operating temp and even after reaching operating temp. the only error code says multiple misfires. [ as when tring to restart you can tell, very rough idle, definitely not firing all cylinders correctly] engine is firing correctly]. my mechanic has replaced the pick up coil in distributor, ignition coil and air idle speed valve. still having same problem. he thinks it is the pcm and wants to replace that next. he also mentioned that the wire harness, in back of the pcm was not in great condition. quite frankly, I hate when he guesses, already $400 into the fix already.is there someone who may have had/heard of this problem or is there a test to see if the pcm is in fact bad?- posted
