When iac is unplugged at cold temp stalls, upon removal of iac I cleaned it, blew into it and no air passed throughSo, just to recap, this is your behavior?
And when you unplug the IAC there is no change?
- Cold Start
- Vehicle stalls and idles very poorly
- Warm Start
- Vehicle idles poorly
So update, vent on driver side of valve cover is sucking in air, also now having rev issues when decelerating slowly goes down on rpm even when rolling in neutralI don't understand.
Do your symptoms change when you unplug the IAC or does it keep acting the same?
Well it never sucked in air before? So all the re routing fixed it?Do you happen to have a copy of the service manual? If not, use your favorite search engine and look for it with "filetype: pdf" inserted after the terms. remove the space between : and p
Yes, thats the fresh air make up tube, it connects the engine to the intake to draw in filtered air from the intake plenum. So that the PCV system can function.
