I've been debating just getting rid of it.

I dont know if this is normal.... but my IACV leaks out the adjustment screw and the yellow seal right next to it.

no that isnt normal or at least i wouldnt think so.if you do get rid of it however get ready for some driveability issues..since i wasnt able to put my IAC valve on my car due to the fact the stock IAC valve is not the same as whats on an R33 RB25DET i just blocked it off. i have since had it tuned this past weekend and i thought that part of the driveability problem would be gone but sadly i was wrong. the car runs great but if you are hardon the gas at all and then you lift your foot off the gas you need to keep your foot on the throttle to modulate the gas as you come down in the rpms. if you fail to do that the car will stall 100% of the time. the IAC valves job is also to modulate the gas in between shifts and taking your foot off the gas as you are slowing down.

Nice work you stud! This should end the bickering in another thread currently running...zerothread/312838

Actually, could you please go the extra effort and add this to the RB parts thread? I don't think it is already in there but I could be wrong.

Just think of the good things. Your Toe and Heel must be at the top of it's game now.

i added it today...and as far as that other thread is concerned its locked but the person who started that thread imed me early this morning and i had to help him out...during which time i scolded him somewhat on his actions and told him i thought he was a tool ...he apoligised to me somewhat but i think an apology should be sent towards fearsome tea if you ask me..but hopefully he got the hint...well see i guess....

I think he will be a good asset to the RB group, but he's just not accustomed to the way we work around here yet. It is tough love for a while and then everyone starts warming up to familiar names.
