V6 250,000 miles
Ok I did plugs/coils a while back, everything was fine until CEL came on. It was for the o2 bank 1 sensor 2. I replaced that with an ntk downstream sensor but the symptoms are still there. Now it's throwing a misfire code on cylinder 3. I got an obdii scanner and bank 1 sensor 2 voltage does not move at all, it is stuck on 0.04v.
So is the bad reading causing the misfire or is the misfire causing the bad reading? I'm not sure which to address first, but i think either somethings wrong with the sensor wiring or cats are no good.
I have a confirmed cylinder 3 misfire code and a pending bank 1 lean code right now since I've cleared it.. any help on where to go from here would be appreciated.
