BrianZ06 Posted April 25, 2011 Report Share Posted April 25, 2011 Ok I just got thru replacing the water pump,t-stat, and a new radiator. Not a fun job but anyway the jeep stalls when ever it feels like it. It does this maybe once a week or everyday. Now the question if I tap on the pcm I can make it die and stumble. I unplugged the connectors and cleaned them and installed some dialectic grease and this worked for a couple weeks but now it's back to the same problem. New pcm or ?????? Im stumped.

351mach11647545510 Posted April 25, 2011 Report Share Posted April 25, 2011 New PCM, buddy just had the exact same thing. I'll try to find out the name of the site he got his from. Some place in Florida, got a new/reman (can't remember) for cheap Quote Link to comment Share on other sites More sharing options...
6 Speed S4 Posted April 25, 2011 Report Share Posted April 25, 2011 My dad had a 96 GC that did the same thing when it was new off the lot. Turned out to be the PCM. Quote Link to comment Share on other sites More sharing options...
BrianZ06 Posted April 25, 2011 Author Report Share Posted April 25, 2011 It has to be the pcm. I have changed or replaced everything else. Then one day I read about the pcm connectors and played around with them being able to make it stumble and almost die. I cleaned them up tightend them down and thought I fixed the problem untill yesterday when it started to die again,that is when I tapped on the pcm body and made it die. Sounds like a new pcm will take care of it. I found this one here. I think I can get it for 199 shipped and feedback looks good for it's worth. http://cgi.ebay.com/ebaymotors/1996-1997-1998-Jeep-Grand-Cherokee-COMPUTER-ECM-PCM-ECU-/110428283202 Quote Link to comment Share on other sites More sharing options...

BrianZ06 Posted April 25, 2011 Author Report Share Posted April 25, 2011 Thanks I needed one today so I bought an autozone preflashed and it fixed the stalling. JCJ sounded like it would have been a good choice, I just saw the reply to late. I now have a new problem. This thing is starting to be a big headach.
