IAC doesn't seem to be operating correctly, actually seems to be shut(extended) and not move at all. Swapped with a known good IAC and same result.
Tested the leads for the IAC;
Key on there is 12v+ at B&D, Blu/Blk strp and Grn/Blk strp
Now it is my understanding that initial key off should reverse polarity, and apply 12v+ to the opposite ports, A&B, but it doesn't.
When I turn the key off, and until complete ECM shut down, 12v is still applied to B&D.
A&B never have any voltage. Something wrong with this picture?
Thanks!
