Does it only happen when you accelerate hard?

Are you able to check TPS voltage at zero and 100 percent?

What vehicle? What PCM? What T/B?

Is it tuned? Do you have any logs?

People, you have to provide information when asking a question. We aren't mind readers.

If it's a cheap Chinese TB, your just going to have nothing but trouble with it. I've dealt with two ove them and swear never again will I do that. Switched to a Nick Williams and was trouble free after that. The first one full of codes, never could get the tps dialed in and drivability was crap.

I was having same issues as op, sorry forgot to provide context.

I tried IAC, TPS, Vacuum lines nothing cleaned it up and fixed it for good. took it to get tuned regardless and i asked about it and they said "yeah it was all in the original mail order tune" got it squared away car runs great.
