You wouldn't by chance be reading your o2s through an interceptor gauge by chance? Only reason I ask is that i had bank 2 on my gauge showing 445 and my readings came up as normal on bank 3 on my interceptor gauge.

WTF! I went out just now and set it to bank ******* "3" AND its working fine. Im so happy and pissed at the same time.
Dude seriously THANK YOU for chiming in! I spent ALOT of time trying to figure this out. I tested wires all over the place,swaped the o2s side to side 4 times,cleared codes,I exchanged the o2s for new ones (under warranty),I was even gonna throw another pcm in the ****** thing. I feel so stupid! But I dont give a **** cause im happy HAHAHA!

Wow that is a trip, what are the chances of that.....man for some reason after reading your post I wondered if that could be it. I'm so glad I could help ya. When I first put the gauge in I thought that was strange how it read like that, must be something in the way the interceptor reads the pcm. But cool now that ya know that nothing is wrong with your car.

Yes big relief! You have to wonder...why would they put it as bank 3 and not 2? The real # for the bank is 2. If you look on the paper they send with the gauge it has all the things that can be done with it but look at it...it dosent list bank 3 or it dosent tell you to not use bank 2! But I did notice when I first got the gauge in the setup it had a bank 3. I thought that was for vehicles with 3 banks so I didnt think anything of it.
Seriously buddie thanks a ton!
