]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
