As soon as the TPS got here, we replaced it. and the idle STUNK! it was worse than when we started. We played around with it, and nothing changed. I was thinking we should not of touched the TPS.
Well, then we moved the throttle cover, (plastic piece over throttle body, and the cruise control and throttle was COMPLETELY loose. tightened and then the idle all the sudden purred. Took it out for a test drive, did everthing to try and make it to surge and buck, but wasn't able to. There was still a ever so slight surge, but that will be gone when engine mounts get replaced.
Problem SOLVED=TPS and throttle bolt
Wow, what a month....
