I have the same problem in my '99 Am told ip

 

Did you resolve the problem ? If not, it sounds like the prob mine had @ 165k. Started with Crank position sensor. Replaced. Started throwing IP code, and CPS code + another code I can't rember. Sounded like a cummins and reved on it's own. Tracked it down to a shorted wiring harness @ the back of the valley. A small smurf tube had worn through on a metal bracket and wires were showing copper. I've put 13K since finding it with no prob's. I can send pic's. gewehre@aol.com.

 

gewehre -- did your problem occur all the time or only after it had warmed up? I'm having the same issues but it only stumbles when warm. It does sound like a cummins when it's cold and I rev it up a bit.

 

Problems occurred at random. Started out mostly when driving and warm and got progressively worse until it was nonstop. Didn't know whether it was an ECM problem or a connector problem or a wiring harness problem. Decided to go the cheap route with no tools required, it's called the wiggle test. This is where you start at the firewall and wiggle the wiring harness just slightly until the problem goes away, then backup until the problem occurs again. This has got me within a 1/2" of the problem. The trick is not to move the wiring harness so much as to disturb other parts of the wiring harness. Don't know what I can tell you other than a contact number. Hope this helps.
