I lost a great video of me sticking my finger in there and it whistling like crazy. The hissing sound that I've been hearing is definitley coming from that spot. Also, as suggested I plugged a&b of the ECM and placed in start position and you can hear it trying to extend the IAC constantly.. it sounded like a stuck dc motor.
I have the valve out - from the tip to the base the cylinder is out maybe like 3/4 of an inch. But it's does not manually move. Any way to test it? fix it?
Question, does the head penetrate fully inside that chamber? Is that the open or closed position when it does? Right now(as you see it) now the head appears to be hidden inside the hole - how is that also open? It's unclear what's it's closing.
Factory oem is about $60 + shipping.
Would you recommend this replacement part. $16 with shipping included!
