Hey everybody I have a 1996 Grand Cherokee that's been having some sort of a ground issue I believe. It has also been stalling from time to time at idle after warming up. I read a thread that talked about 2 screws on the PCM but I'm not able to figure out what 2 screws they're talking about. The XJ has been doing all the things they were talking about in that thread. Could use some he;lp here. I took the now completely dead battery to a local auto parts store to have them check it and they said it was in good shape. So anyone have any ideas? Please help!!

Need more info. for those here to assist.
What motor do you have? the I6? or?
As far as the stalling... could be a number of things... ASD, IAC, a fuel delivery issue, etc. Need more specifics on the When, what, why(the root cause), where, how.
Grounding on the PCM, there are diagrams all over the net for them. I'll let those that have had that issue and solved it jump in on that side.
Now there could be the possibility of more than one issue to fix.. have you tested to see if your alternator is producing the correct voltage still? (since something is causing your battery to go completely flat)
now this below isn't just a grounding solution, but a set of plates that people have made as this has been a known issue with the GC's for some time.
It keeps the PCM and connectors in place so that it doesn't vibrate loose even the slightest...as if it does, boom... you've got an engine shutdown on your hands each and every time....and it tends to happen after the vehicle is already up to op temp and being driven.
Toss an eyeball. Not saying this IS your shutdown problem...but this is a well known issue with them... and many have successfully used this type of a fix for it.
GC's (while not alone in it).. do have their fair share of electrical gremlins.
