Replying to: jeephelp (Apr 07, 2009 10:04 pm) 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 |

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? |

| 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 | |

My husband just bought this 2000 Jeep Grand Cherokee. He knew that the sellers were having problems with it and they showed him all the things they had done to try and fix it lately. He still thought it was a good buy. We now have a "Headache"...or lemon!! The problem is, you can drive for an hour, even two hours. BUT if you stop for a minute the jeep starts spitting and sputtering, it then shuts off. You have to sit there for a good 10 minutes to restart it. It will restart right away but it will spit and sputter. After 10 minutes it starts fine. We checked the ecu (computer), supposedly it's fine. He just replaced the ignition coil (chrysler told us to) didn't seem to help. He did say that it runs a little better now that it's changed (or so he thinks). We are leaving for vacation in a few weeks (over 800 mile drive) and we have two small children. We don't want to be breaking down on the side of the road. There have been many things replaced but I will have to get a list. He just drove 3 hours away and called me to tell me that he had to add transmission fluid twice because it keeps running out and shutting off. I guess it sprayed all over the underneath of the Jeep, all the way up the back window! (The transmission has been replaced recently). Could it just be a seal bad? Another thing, he just mentioned the check engine light is on and flashing. We are going crazy over this whole situation!! PLEASE someone help us!!! |
