Thread: iacv aac valve question

so im hunting down vaccum leaks as to whats contributing to some lean cruising conditions...so im here checkign




ive alreadey cleand this out and had a noticable diffenrce at idle,not having idle problems but made it more smoother...

now my question is this... when i shake the iacv and aac unit im my hands...i can hear the plunger (whatever ya wanna call it) ratting around..like its not closed or fully openin..

when i cleand it out i noticed what seems like the little spring has no more'' spring'' to it....and didnt close the plunger..


with what is in the pic.....if i blow or suck thru the hose..air is moving either in or out....is that supposed to happen??? or do i need a new iacv and aac,i saw them on gspec but kinda dont want to drop more $$$ on someting i ddint need(like my new 4wire o2)...

any inpput ? im sure someone has one access able to see if its similar?
