?? No it doesn't. Other peeps are saying by pulling the plug on the IAC revs rise, that implies that the valve is fully open when off which is in direct contradiction to every expensive I've had on a 5. I.e. Everytime you pull the plug on the valve, it closes/turns off/revs drop.
This is on both aftermarket ECUs and stock FWIW
What yourdescribing Pete is the correct operation of the idle valve I.e. It adds supplementary air when required to maintain the idle target.
