Throttle body idle screw
While looking into the whole block off plate debate - I decided to look around the engine bay and see if I knew what was up. The only thing I can't seem to figure out is the screw on the TB that everyone says to adjust the idle. I'm not really taking the car apart looking for it - but they say it's a small flat head screw on the firewall side of the car adjustable from the passenger side. As silly as this sounds- does anyone have a picture or a better description of this screw? For the life of me, I can't seem to spot it. The manuals don't really mention it - just adjusting the BAC for a turbo II s4 like mine. The posts all have "I'm adjusting the butterflies." and whatnot. So can I get a little bit of info on this screw? Thanks.

The BAC has a idle screw on the turbo II - but I'm looking at how it's done on the throttle body on a turbo II. This is the premice behind removing the BAC and EGR and all those other letters.

Man, with all the posts around about crappy idles after removing that BAC, you still want to do it? Read Kenteth's thread that was started a couple of days ago...

I've heard mixed results - and since mine is jacked up as per the FSM - I was thinking about trying something else. And I figure that I can put the BAC back on if anything happens. But before I really get started - I want to know where this screw is.
