Hans,

Of course if IAC is at 0, then u have a vacuum leak but that could be at primary throttle blade. I posted a procedure for adjusting Min Air a few months ago.
Basically u want motor to idle at just below ur target w minimal IAC intervention
ie 10-15 steps. TPS V will need to be adjusted after each change.
