    You can drill/tap the back of the manifold to accept a 2 wire IACV. The right most bolt hole should already be there.

    yeai did that today and the car runs like ass..all the holes are perfectly lined up though..
    it starts and bounced back and fourth between 2k and 3k...but the wierd thing is it did that and we were bleeding the coolant..5 mins after we bled the coolant there was a loud pop and the car idled perfectly at 800rpm..well i let it sit after that..went out and started it and its right back to the bouncing idle..idk what it could be..

    My Y8 manifold was giving me absolute hell and surging idle until I sealed the IACV. Unplug it and see how it runs. If the idle drops down to where it should be, that means the IACV it's self is broken.

    Actually from re reading it I think you have an automatic Y8 manifold, which is a bitch to get working right.

    bypass the fitv with the coolant lines, then unscrew the fitv from the tb, cut a piece of gasket material the same size as the mating surfaces between the fitv and tb bolt it back up and see if the thats the end of your woes. if it works leave it that way, get some sort of block off plate, or a manual tb.

    im running a manual TB already...i will try to bypass the fitv..but im going to pull everything back apart and redo everything with new gaskets,at first i thought it might be because of the drill/tap work..but ive checked and everything is the way its supposed to be.

    im guessing its a vacuum leak somewhere..the fitv and iacv are from the z6 manifold which was running the car perfectly the same day i pulled it off and swapped it to the y8 mani..
    so im going to pull it apart and redo everything when we get some warmer weather..
    i know the drill and tap is right because ive searched for others that have been done and i did the exact same thing..so idk ill figure it out somehow
