IACV / AAC Failing RB25DE Neo, R34

[_scott]

Hey all,

I've been hearing some weird buzzing from my IACV lately. Whenever i turn the ignition to ON, it starts to buzz.

When I pulled the IACV off to see what it's doing, I noticed the valve is moving back and forth just ever so slightly. Check the video below:

I'm not sure if the valve is trying to open itself all the way and is getting stuck or if it should only open halfway like that. Any idea if the IACV is on it's way out? My car does idle higher than it should be, so wondering if faulty IACV may causing it.

Mine started doing that buzzing and then started idling terribly shortly after, it seems to be shot. Maybe try cleaning it? I did clean mine but it didn’t help.
Currently just running a block off plate until I figure out an alternative to the oem valve

Thanks, I kind of suspected it's on it's way out.

I gave it a clean a while ago, but still seems to have the same issue
