Hesitation and stumbling while accelerating, engine running too rich, or too lean, it also has input into the transmission for shifting points. That's all I can think of off the top of my head.

Yep. That could be a symptom. I take it that the wiring problem you found didn't fix your problems.
Check for vacuum leaks. That could have your idle too high.

There's not a whole lot that could go wrong with replacing a TPS, unless you were unlucky enough to get a bad TPS from the parts house. Maybe you disconnected something along the way that you forgot to reconnect or knocked a vacuum line loose. That wiring thing sounds like if it isn't a problem now, it could soon be. Fix that and go over the connections.

TPS ended up being bad. Not just 1 but 2 were bad.
Jeep would ideal at 1200-1800 RPM, was just plan crazy..

Very close t it. Now he's saying it has a cold start problem.. He has to feather the throttle to get it to start. I'm pulling what little hair I have on this one out.
