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

      Evening fam, Pretty much what the title asks, I have looked all over and can’t find a proper answer expect one post from almost a decade ago which is vague. ive seen photos and they look pretty much identical, would an r33 GTR N1 reo work on an r32? reason I ask is they are cheaper to buy… $700 compared to 1k+ for an r32 n1 reo

      Couldn't help myself, had to start putting it together.... It really is a solid bit of kit.  Probably stronger than i would have made it myself to be fair! 🤣🤣 Sweating like a pig after that.  Bloody hot and muggy day today, time for a swim now!

      R34 GTT idle problem

      By silviaz · Posted

      Yeah was thinking that. I've had the car go lower idle possibly around 650rpm every once in a long time after pouring fuel and would sound quite rough like a misfire, almost like it's shit fuel or something but who knows.

      GTR Festival (Aus) - 2025 - Stagea Alley

      @Wazmond you are correct, my bad, was not my intent    https://www.facebook.com/share/15ZMn5oXtc/ Updated Event (so its not private and can be shared easier)  Attempting to coordinate a big push of Stagea's to this years GTR Festival. Great event last year and hoping for the same this year.    I've emailed them to ask to set a location aside for the Stageas for the show and shine - they are happy to do so if we can get them numbers, I'm happy to keep track of that. Entering as Nismo category.    I'll be road tripping up from Melbourne, would be cool to convey if people are interested, maybe there is SAU convoys from each capital? If you have ideas about that let me know.    https://gtrfestival.com.au
