High/Hanging Idle - ZR-1 Net Registry Forums

ssmith95 · 48 Minutes Ago

I made some headway this evening. The vacuum line on the air horn was not connected, must?ve come off when I was reinstalling the plenum. That helped to bring the idle down considerably. With that leak fixed I could hear the iac was sucking in a ton of air despite having 0 counts. I stuffed a rag in the throttle body and just covered the iac inlet. Sure enough, that brought the idle down to 650.

With that being said, other than it just being the incorrect IAC is there anything else that would cause that passage to leak?
