check engine light came on. hooked it up to scanner and said "bank 1, sensor 1 heater circuit malfunction" so im guessing that means its either not heating up properly or somethin... so i replaced it. the light went off. came back on like 3 days later. replaced it again. came back on like 2 days later. replaced it again. came back on again... so ive just been driving it for like a month like that. its only got 1 catalyctic converter so i know its not that because the other 02 sensors would pick it up if it was the cat, so the scanner would say "catalyctic converter falure" there is a tiny exhuast leak on that side right befre the o2 sesnor somewhere (cant find where its comming from) but that shouldnt affect the 02... anyone have this problem?
