I just did the TB mod and when I got the system back together the idle fluctuated between 1200 and 1400 RPM https://www.nopistons.com/forums/pub...1047683358.gif . I reset the TPS. Is there something else I have to reset? I was thinking the BACV, if that can even be adjusted.

thnx

Check everything for ait leaks first, you may have knocked off or forgotten a vacuum line, or your O-ring may have fallen out. Also make sure the throttle plates are closing all the way now.

Well I adjusted the idle and checked the vac lines and now it won't idle at all when its cold. https://www.nopistons.com/forums/pub...IR#>/angry.png Runs great when its warm though. https://www.nopistons.com/forums/pub...IR#>/smile.png I was afraid the TB mod would cause this but several people said that it ran just fine when cold. Did I do something wrong or should I have expected this?
