RE: Stepper Motor
As said by mike its the intake air control valve. I know there is a Chev IAC that will fit on the 3.9 but not the 4.0. The reason I think it is the stepper motor is that the vehile did not idle most times when started warm. It would start and then just quit. I tried just turning up the idle and it works when the stepper motor is malfunctioning but then idles too high when it works. So the one time it worked I disconnected the wiring to the stepper motor to freeze it in that position and now it idles fine. Hence the stepper motor. I know the idle air will not be accurate with change of altitude or exterme temperature changes, hence I want to replace it.
