Hello guys i have a honda civic ek ej9
i swapped with B16A2 but my wirings is from d16Y7Everything runs perfect I have a connected vtec and whatever else was needed .the only problem I have is with the oxygen sensor when it's cold the car messes up like it's running on 3 cylinders once it warms up it works better but makes some cuts (no ecu faults)
when I take him out of the plug the car runs perfect
(Ecu fault 41 code)
I have checked the oxygen sensor it seems GoodI run P2T ecu
does anyone have any idea?
​​​​​​​maybe to transfer the wires from the primary sensor to the secondary one?
