    moved.

    I would think the IAC that is for your TB.

    But i think you'd still need some sort of adapter.

    makes sense, was thinking that becuase the pintles are different between the grand prix and the one I took out of the throttle body (northstar), plug type is the same. Could be different wiring though. the problem im having is the pintle keeps extending all the way out and interceptor reads 255, which i believe means it trying to open all the way to bring the idle up but cant because the pintle is all the way out and it cant bring it back in to raise the idle. I could be totally wrong tho.

    I havent even really got a chance to try it. been working on the car all winter drove it for a bit now my iac is giving me trouble. I have a parts GP so i can steal the stock L67 TB off it and port it if I dont like this one.

    N*'s rock...IMO.

    The IAC is the same IIRC. Aim for one for your TB, but if you have a spare GP TB laying around..compare.
    I drink..so consider that when reading my posts.

    IAC seems the same except the pintle. I tried to use the GP IAC and it idled fine but then shut the car off and wouldnt start back up. Took the IAC off and the pintle had fallen right out. Going to try find a cadillac IAC at a junkyard and see if it does the same if it does Ill have to check the wiring. Thanks for the responses!
