I have had this issue since I have finished resurrecting my GS-T. I have replaced my IAC Motor multiple times and still the issue remains. I cant find a wire diagram for the IAC motor to save my life. Every motor tested good with that ohm test across the pins. My car stalls all the time when i engage the clutch and the rpms drop, it won't catch itself and stalls. If i let the rpms come down in gear and engage the clutch around 1000-1500 rpm it doesn't stall. I also have erratic idle issues, and idle surging. A diagram would be greatly appreciated, also any advice or ideas would be awesome. Thank You for your time..
 
I would run a boost leak test and fix anything you find. Your issue is most likely due to a boost/vacuum leak.
 
i tried that no vacuum leaks, well there were but they have been taken care of.. i get a code for the idle air control malfunction. i have gotten this code with every one i installed. I am kind of starting to think that maybe I have a bad ecu. Sending a bad signal or something. I really hope not tho
 
Did you check the resistance of the pins? Make sure each one you put in is good, also check the FIAV.
