Re: Help - New throttle body weird behavior.
It's my guess that it was vaccuum holding it open...but it would never come down till I blipped the throttle. So, with the secondary spring, it now shots.
The lower RPM hang is not a vacuum issue right now, it's actually the TPS opening the TB open. But, it only does it after driving, if you blip the throttle, it will close up and idle down to 800 like the tune commands. I'm going to mess with the adjustment screw and see if I can't fix that too.
