Infamous stalling problem identified, temporary cure 1997 grand Cherokee
well after replacing just about everything under the hood of my jeep to try to fix this stalling, bucking problem. i have found a temporary solution. It seems the connection on the middle(white) connector that goes to the pcm has some sort of problem keeping a connection. Whenever i wiggle this connector my jeep will shut off or for that matter stay on. I have zip tied the connector almost pulling out of the pcm and that seems to be helping wonders. My jeep would buck, stall, backfire, shutoff, like many others i have been reading about. i was wondering if anybody had any other suggestions to a permanent fix. do you think its the wiring harness or the connections on the pcm? and also why would my jeep buck, stall more if its just rained or wet outside? i have spent many months and tons of money trying to fix this problem, and come to find out its something just a simple as this. one more question. why would my check engine light randomly come on and then go off when its bucking/ stalling i get codes. 12/14/42/43/55. i hook it up to a scanner and i get MAP voltage to high, and Primary Ignition Coil A. and then sometimes it passes with no codes. any help or thoughts would be great?
