i tried adjusting my tps with this yesterday, and when i started up the car and it warmed up it had a significant bounce in the idle.

i adjusted it so it wouldnt do that. i just need to do more fine tuning on it.

I was told (by Racing Beat) that you have to adjust it after the car has reached operating temp, but while its not running. That's how I've always done it and my car runs fine.
