Can someone post a picture or tell me where the hose off the IACV goes. I took mine off when i went to megasquirt but now im putting it back on. I have no idea where it goes. I may have taken that piece off ? Any help is appreciated. Thanks

Um, intake tract before the throttle body? I mean, it would have to.

Also, the IACV is garbage and should be treated as such.

Okay, so it connects to the intake tract, before the throttle body, and tees up with some other nonsense that goes under the intake manifold, kinda. You can see in this picture that it is hooked up with a blue hose to a tee, which comes off the intercooler cold pipe.



then the other end goes to the intake manifold, post throttle body.

That is the IACV, right?

no that is the cold start jazz, the AICV is mid plenum above the injectors.

Air Regulator (Cold Start Idle) @ Below TBFICD + AAC = IACV @ Mid Plenum
