97 jeep grand Cherokee stalling
STALLING PROBLEM SOLVED !!!!
Thanks for all your help everybody. I too have been chasing the "Jeep Ghost"... -for 6 months, and have successfully exorcised it from my Cherokee... I did the obvious things first: plugs, wires,rotor, cap. still stalled.next obvious replaced coil. -still stalled, next to mechanic shop for diagnostics they concluded crank shaft sensor, replace new, -still stalled a block from their shop ! another shop "replace the crank sensor with a mopar sensor" 2 days later -stalled. 3rd shop for diagnostic test and 2 days of drive and testing " uhhh, have no clue...." back to first shop "oxygen sensor" "-ok change it " stalled on way home... desparation with head hanging low....TO CHRYSLER DEALER FOR DIAGNOSTICS !!!! $100 "probably your ecm...? you've replace everything else..." Well, throughout this ordeal i kept jiggling the harness plugs disconnecting reconnecting cleaning and cable tie securing them to the ecm body. stalling kept getting worse and worse. had to tap on ecm to get jeep to restart after "high speed and dangerous" stall outs !!! after 6 months of troubleshooting (and stalling !!!! ) confirmed that tapping on the ecm body with pliers, screwdriver, rocks !!! the jeep would restart. while all the time following this thread and everyone elses pains and successes. after believing I had located where the ghost was hiding ( ECM) I opted to buy a re-furbished one at $158.00 against an $800 one from the Chrysler dealer. I received it in 2 days, installed it
4 WEEKS NOW AND NOT THE SLIGHTEST HICCUP OR SNEEZE ! ! MY RECCOMENDATION ???
ON ANY VEHICLE, IF A STALLING OR STRANGE SYMPTOM APPEARS, CHANGE THE ECM WITH A RE-FURB FOR $158.00 !!!!!! most of what i did was all following logic. no one in 6 months new enough about this to be able to tell me what I have learned as I have learned it. as someone stated wisely earlier in this thread " a computer board sitting on your firewall in heat and cold for ten years is doomed to fail..."
-I'm surprised they last as long as they do... I bought my re-furbished ECM from a company in Dania Beach Florida. they seem to have a lab where they open and actually re-furb them. and seem to specialize in this. I have been lucky with the one I purchased. Im including their contact here as they successfully helped me to purge the ghost from my jeep. I felt great putting the old one in the return box and taping it up extra securely and knowing I was dropping the ghost into the postal mail box. I got the last laugh-
I hope this helps many.
