Thanks Graham, missed that. That tells me the IAC is not controlling the idle speed (zero count) at the point it's stalling. We have found before that the base mechanical idle adjustment of the throttle body sometimes has to be redone when the intake has been ported. To me the next step would be to readjust that. I have to do a search but it's out there in the tech forum.
