So i picked up a project car, 150,000 miles I'm guessing cuz the ac module was missing for who knows how long and last miles on it was 145,000. But the issue is, the previous owner has the downstream o2 plugs reversed, so the blue was on the green and the green on the blue connectors, so will it throw a code for the opposite bank? My driver side plug (green) was in the passenger o2 plug and i was getting a bank 1 sensor 2 code, then i switched it to the same colors and now I'm getting bank2 sensor 2, so is it because the wires were crossed? Or is the green plugged that's missing the housing bad? I'm thinking since bank 1s female plug was in the bank 2 plug that thats the bad plug. But then again if it would've read regular even though they were crossed then my female collected is bad..... Help!!!
