[Es2] still looking for unstable idle problem

The first thing that I think of is the idle switch in the throttle
position sensor. Make sure the TPS is adjusted correctly, and that the
idle switch gets engaged. If the computer doesn't know that the car
should be idling, it won't go into idle mode. I really haven't seen
those go bad on AANs, but it is easy enough to check. Do you have a
diagnostic tool (like ProDiag or Vag Com)? Have you checked the blink
codes? Doing a pressure test of the system is always a good idea, but
check for trouble codes first.
What code are you using now?

I have change the MAFand ISV and cannot figure out what could be causing this? Anyone have any idea's? I thought maybe a vacuum leak but it seems like I would see that on my boost gauge and it would do it cold as well. Any help greatly appreciated as always.
