Hi Al,

Yes, I had disconnected the IAC until I got it idling with very light throttle application, so now I am adding it back into the equation.

Much earlier in the process, I verified that the IAC was open at start and closed once the engine warmed up, but as we all know, things change... today after it was warm, my finger was still getting sucked down on the intake, although it didn’t change the engine running.

I used the CAN bus testing function and with the IAC out of its port verified that it moved; except it moved to the piston separating from the valve! I got it back attached or at least it appeared to be and the CAN test on a running motor showed that it does operate and no finger sucking at closed.

Is that normal for the shaft to separate, or should I source a new part and do you remember the model? I think it might be the Jeep type?
