04 V6 3.8L RPMS get stuck, previously had extremely rough idle, then turns up asymptomatic.

Sound like the TPS?

Any other ideas?

Got stuck at around 50 mph 2,000 RPMS and car won't accelerate or deccelerate.

Thanks Sweet 03 GT!

Little rude 50daddy.

New symptom today, got up to 3500 RPMS going 5-10 mph trying to get on the freeway still sound like TPS or IAC valve? Got the new IAC valve to change out tonight, still wondering if I should mess with the TPS?

Thoughts?

Thanks for any helpful responses!

i would look up specs on tps and see if its out of range. also make sure you have no vacumm leaks which will cause weird idle

New IAC valve in and test drove fine. Waiting a few days to see if anything on the TPS needs to be tweeked.
