hi i just wapped a b20b into my ek (d16y7) and im having trouble with the wiring. We used my d16 harness along with a jumper harness and p75 ecu and it not idleing right, we tried everything we keep getting a code 14 on the dash and its the iacv but we rewired it to a two wire and it just idles at like 100, and when you rev it it keeps going up and down between 2500 and 2200 really fast.I thought it was a leak but ive checked every hose possible. I tried a different iacv and still the same im not sure what to do i kept messing with the wires but no luck any input you have please post thanks in advance
