i paid a shop to look at it the guy told me somethings not right with my O2 wiring ground or something rather he was talking hella fast, just picking up what i could i got cross wire to the o2s both sides!! and its going back to the ecu and or could be a failing ecu!! he said track it down or keep paying 90 an hour for him to track it down, so anyone now what voltage my O2 wiring should be at and what color wires do what? And what range each wire should be reading? so i can check this out, anyone know what would make it do such a thing? he also said that other sensors ground into the same wire going back to the ecu so they could be working half ass aswell!! ideas please guys!THANKS!
