i pulled and cleaned the iacv thingy (pretty easy with this isis plenum lol) it was pretty nasty in there. put it back on and adjusted the idle screw on it and it made a small difference. and then i got nosey and pinched off the vacuum hoses going to the iacv. if i pinch off the one coking directly fromthe intake plenum the car dies completely. and if i pinch off the one coming from the intercooler pipe it just idles down alott. does this mean the aac motor is bad? or that i might have a stealth vacuum leak...
