    Guys and girls.
    I recently fixed my AC and realised the IACV and AAC connectors had been switched around.
    When i fixed this issue i ended up with a weird hunting issue whilst the car was warming up.
    The weird thing is it stops after the car gets to temp.

    I am thinking IACV valve is screwed or maybe the temp sender is on the way out.
    Looking for some solid advice before i start spending money on parts i dont need

    Thanks
    Rob

    Hunting can be caused by vacuum leaks -have you pumped it up to check?

    Shouldve said

    The hunting goes away once warm.

    Plus i'm getting more boost than ever now (13.4 psi)

    Just compressing some ecu talk video, if i can get it small enough ill upload results as well

    Does it idle better with the AAC unplugged?

    ECU TALK videos

    compressing the video to upload (video was 1 gig) has taken all readability out of the gauges..

    :(

    is the ecu mode selector all the way anti clockwise. mine was a quarter turn off and it played up exactly like that.

    Ok

    So I disabled the AAC connector and warmed her up this morn.
    The hunting went away, but it ran as rough as all f#!k.
    Missing and almost stalling like a real whore. Wasn't overly impressed tbh.

    But the hunting went away.

    Obv something wrong with the AAC IACV thingy.

    Can this be repaired easily or is a replacement in order?

    If it needs replacing I may take her off the road for a while do another plenum pull and get the injectors serviced as well. Plus the O2s cos I've got a lazy one

    Oh and ecu is all the way clockwise. And un-chipped :(
