#502 of 1069 1996 Jeep Grand Cherokee stalling problem FIXED by cc757

Apr 07, 2009 (10:25 am)

After chasing our tails for weeks and replacing sensor after sensor, I had a guy come to my mechanics shop and hook up special diagnostic equipment just for the Jeep. He found nothing. As he was walking away from the car, it stalled. He left the key on, and hooked up his equipment, nothing....the computer or PCM was shot. So I bit the bullet and got a new PCM and the car runs fine. SAVE YOURSELF THE TIME AND MONEY AND START WITH THE COMPUTER, THEY ARE ALL DEFECTIVE AND WILL DIE ON YOU EVENTUALLY. THESE THINGS GO BAD AND DON'T SHOW ANY CODES. THIS WILL CAUSE ALL KINDS OF HAVOC WITH VARIOUS SYSTEMS AND WILL DRIVE YOU NUTS TROUBLESHOOTING. YOU WILL SAVE YOURSELF A LOT OF HEADACHE. Forget about quick fixes... zip ties, backing out screws and all that, it won't FIX the REAL problem which is a faulty design by Chrysler....and they know it. I personally will never own a Chrysler product again. By the way, does anyone want a nice used Jeep??

Hi tmpga,
I had the PCM (computer) replaced. So far so good. It's only been a couple of days, but it hasn't even tried to stall. I put a more detailed post up on 07 April. I had a guy come out with some Jeep specific diagnostic equipment. He hooked it up and found nothing. No codes. A couple of times HIS computer screen blanked. After he disconnected, the jeep stalled. While the key was still on, he hooked back up to look for codes and got no readings at all from the computer. (Bad motherboard so to speak) So the computer was shot and I got a new one. $400 bucks. If you go down that road, DO NOT use Auto Computer Exchange from Davie Florida. I have heard nightmares about their products and customer support. Good Luck

#508 of 1069 95 Grand Cherokee idles rough at low speeds by kimjones1

My 95 Grand Cherokee idols VERY rough and accelerates slowly from 0 to 60. Once I get her above 60mph she is happy.
There is also the smell of rich gas.
We changed the fuel filter and filled it up with gas treatment and premium gas. Helped a little but did not fix the problem.
Could this be the o2 sensor?

#509 of 1069 4.0 engine intermittent stall by finisher

Apr 21, 2009 (2:36 pm)

1996 Grand Cherokee 4.0 engine. Over the past 4 - 5 months engine will hesitate/stall for a split second and then continue running fine. Some days problem will not occur at all. Occasionally at stop light engine will stall and restart w/o a problem. Hot or cold does not matter. Flat ground or climbing a hill does not matter. Example: While traveling at 65 mph with the cruise control set, engine will stall for a split second and then continue running fine. Lights, gauges, radio, cruise control set light will remain on and when engine restarts cruise control remains on and speed is maintained without resetting cruise control. New plugs, rotor, cap & wires. Check engine light does not flash or remain on. Any ideas? Dennis
