]Check out this video. My idle bumps just like the vacuum between 550-700rpms. It does this after the car has fully warmed up. Cold start the vacuum and idle hold firm until the engine gets up to operational temperature.
Things I\'ve done: full boost leak test, and repaired the leaks I found. smoke test, and repaired the leaks I found. My question?....what else could cause this? Sticking IACV maybe???? oh yea...it\'s a 3rd gen 3sgte. Fully built...etc...most of you are probably familiar with my build. If not it\'s in the my project section. http://s1190.beta.photobucket.com/user/bsa...403873.mp4.html ![]() This post has been edited by bsamps4: Nov 12, 2012 - 7:18 PM -------------------- ![]() |

the IACV is plenty big to run fast idle up to 2000rpm, the throttle plate should always return shut, it has a little pinhole in it for vacuum release
