Try to find someone with evoscan and hit the activate button for the idle screw and see what the idle goes to.

If I take the IACV out of throttle body and turn ignition on, how much should it move (distance). How many times should it do it???

mines idling like 2300 starting and staying there while in neutral car runs fine when driving until clutch is needed or in neutral.
