Iacv
This is for all the hardcore guys that have taken apart an IACV.
when you look inside the ports you will notice that there is a rod that turns and there is a metal plate that spins with it aswell that closes and opens the actual port.
well i am having an idle problem which is the car going from 1200-2000 up and down.
so took the iacv apart and i noticed the metal plate that supposed to open and close up was seized because of build up etc.... so i sprayed carb cleaner and flooded the entire iacv (off the car in my hands ofcourse).
then on the side of the IACV there are two screws (not the green part but the other side) when you remove that the casing comes off and you will notice that there is an actual turning mechanism there.
so using a needle nose plier i finally got the plate to move freely with no play etc and cleaned the **** out of it and put it back together.
Now i am still having the iacv problem.
my question is what else could it be? do you guys think the mechanics inside the green sensor plug part on the iacv is fauly? i wasnt able to take it apart because the screw was really tight.
also isnt the point of the metal plate to open and close like a valve inside the iacv and me actually cleaning it up and making it move freely again supposed to fix the problem???

Are you getting a code for IACV? Or are you just assuming that's the problem. I had a similar idle fluctuation but I fixed it by cleaning the IACV. I have read that it could also be the FITV below the throttle body that is causing the idle problem. I was going to check for that but I don't think my b16 has a FITV .. Also I read a post that if you plug the hole with your finger at the bottom of the throttle body, if the idle surging goes away then its the FITV.
Can anyone confirm if all b16's have a FITV. Maybe that is your problem Jay.
