O2 sensor problem....HELP!!!!
All,
I put on Pacesetter LT's, HiFlo Cats, and a 3 in Y pipe last November. For about a month now the check engine light has been coming on, Code P0157- O2 sensor 2 Bank 2 low voltage. Well, I replaced the damn thing twice and anywhere from 5 minutes to 30 minutes after driving away from the garage, the check engine light comes back on. I monitored the engine on my Diablo tuner this second time around and the voltage right off the bat just drops almost to zero.
Do I have a bad Cat or is it the O2 Sensor 1 Bank 2 that is screwing things up?
Thanks,
Ned

thats really wierd because mine work fine. The ses light i got was from removing my AIR. I know you loose voltage when you put underdrive pullys without an overdrive alternator but i dont think that has anything at all to do with the 02 stuff. Im sure someone will know though
