[Gmecm] $8D IAC stalls engine on decel

[Tomas J. Sokorai Sch.]

Hi guys!

Well, my GM ECMed bimmer is getting almost into a nice shape. Managed to 
correct the engine cuts @ 2000RPM by starting modifications from the backup 
bin I had, but I couldn't figure why exactly it was doing that.... anyway... 
now I have only *one* big driveability problem left:

On decels the IAC throttle follower keeps getting the commanded IAC steps down 
to ZERO. And this happens quite a lot when downshifting, so when it is at 
zero steps, I push the clutch and I get an instant stall.

Any ideas of why is the throttle follower getting the IAC down to zero? 
Shouldn't it be keeping the minimum at a saner value (learned Keep Alive 
steps for example)??
