I installed a new iacv and air regulator two months ago and it hasn’t seemed to do anything. Upon looking through Conzult my iacv is only 15% open at idle and the idle is low and the car shakes and runs rich, as I accelerate and give the car more gas the iacv opens more and opens to 49% and stays there. This doesn’t seem normal. My car seems to think that since the iacv is open that it has a vacuum leak as it richens the fuel mixture to compensate for this it seems like. Is this normal for the IACV to open at these times, if not, do you know how I would fix it?
