1999 Cherokee XJ Limited. Jeep starts with no problem, runs fine. My only issue is it has no *****. Its acceleration is definitely less than desirable. 9 months ago I put a new TPS on it. It has nee plugs. I've had issues with loose grounds before, checked those. It shifts fine (although I feel a bit late, not sure if I'm being picky or not). Even though I changed TPS I'm getting a code PO122 TPS circuit low input. Any takers on this? Everything I've read on TPS has symptoms of jeep bucking or stalling and acting nuts. Mine doesn't do any of that. Any help is greatly appreciated. Thanks
