Okay, we have a 2004 Jeep Grand Cherokee 4.0 inline 6 and we had the same problems. After spending a lot of money on sensors, fuel pump and many other things we decied to start it up and wiggle some wires around too see if it could be a wiring problem. We found a wire in a wireharness that runs along the engine by the fuel injectors. At the end of the bar wires coming out there is a wire that goes to oxygen sensor and it was pinched. After fixing the wire and it has not given us any problems

#869 of 1240 Grand Cherokee Low Idle / Stalling Issue
Sep 18, 2011 (6:04 am)
I got a 1998 Grand Cherokee 4.0L and been having issues with low idle and stalling when going from reverse to drive or just taking off from sitting still. I already replaced the TPS (throttle position sensor) and MAP sensor. Also I backed the 2 hex screws off 1/4 on the PCM computer, still no luck. I know my fuel pump is getting weak and needs replacing but not sure if thats the problem?

I just had my fuel pump replaced today, cranks up good now but still stalls when in gear sitting still or shifting into gear. Also im getting a delayed shift in 1st gear? Below is what all i've done so far.
- New fuel pump & strainers
- New (Throttle position sensor)
- New MAP sensor
- Cleaned IACV (Idle air control valve)
- Backed both hex screws about 1/4 off from ECM computer

I sold my 2001 Jeep and I'm glad I did. But before I did I figured out the problem. It's in the computer. There is a short. There are 2 screws that hold the computer to the base thingy. Remove the screws, put a washer on each screw and screw it back in. I think it was a 10mm, it was thin. It keeps the screws from grounding out the computer. Then wrap the computer in plastic 20" zip ties and tighten it down. Once I did this it stopped the crazy dying with no real rhyme or reason. You can go to Dyingjeep.com for a detailed write up on how to do it but it cost $20. It was the best $20 I spent on that Jeep.
