Hey all, I need a new set of eyes on a problem i have been fighting with. I have just installed a used BBK TB i got from a sn95 member, and i have been fighting a high idle.. starts cold at 2K then settle's into about 1200. I have replaced the IAC but it didn't change anything.. The Car has been checked for Vac leaks 3 times, twice by me, and once by a local shop none were found.. I have also replaced the TPS and it has also be adjusted...Other then the high idle the car runs, and sounds amazing, throttle response is crisp.. The only reason i replaced the IAC was because when i unplug it, the idle drops to around 700 and is steady, i was told this was a faulty IAC. I am kinda out of ideas.. anyone have an idea if i am missing something?.. Thanks Don PS: What the heck is this hole for?.. there's another one opposite of it. they seem to be threaded, and are completely closed. EDIT: It wasn't till i looked at stock photos of this TB that i relaized that peice with the holes in it, are a add on.. I may try pulling that off tomorrow and see if that does anything.
