Hi guys, long time no see. TTA579 is running but I'm having a little trouble on startup. I wanted to ask you guys because I know so many of you are particularly knowledgable.
After what I still believe is a difficult start, the car will nearly stall about twice while bringing the idle down from 1500rpm or so. After the car settles on ~800rpm and it's warm it appears to have little to no issues. If I try to put the car in gear before the idle has come down it will stall, after that time however, all is well.
Following the idle adjust procedure, the car takes a long time to settle after adjusting the idle screw, almost to the point of not adjusting. I've settled on an IAC of ~45 for now.
O2 count shows leanish (300) at idle, but rich with any sort of throttle (800). Everything else on the scangauge looks normal (using buick numbers). All parts look stock except for the cat-back.
If you have any idea what's going on here, I'd appreciate the help! Thanks.
