hey i had a thread made earlier here explaining everything >>>>https://honda-tech.com/zerothread?id=2237810

now i was thinking i did replace the o2 sensor a while ago with the one for my stock 95 dx car d15b7 and like i said it runs fine with a P06 ecu, now do i need to get the actual integra o2 sensor when i looked at autozone they were different part numbers. I think that could be the cause of my problem since it runs well off the civic ECU but not the P75. and theres absolutely nothing else i can replace that i can think of that would help gas milage i've basically done it all. Is this something that i missed when i did my swap and should have replaced?

what replace it, cause its hooked up
