oh you have no cats at all. if the nonfoulers are doing their job limiting the exhaust seen by the secondary o2 then it would definately have to be your sensors. i must have missed you telling me you didnt have ANY cats. ive never heard of anyone trying, but can you switch your bank 1 with your bank 2 and see if the problem follows the o2 sensor?
I was thinking about this problem today. I wonder if I should install the stock exhaust and cats back on and run it to see if I throw the codes with the stock exhaust. If I do throw the codes, it would mostly likely be my sensors. At that point, I could check the voltage of each sensor or just bring it in to Nissan and have them check it. Would that assumption be correct?
STFU pasty. go get a tan or something. thanks for helping us out at the show maing!
Don't be jealous that your panamanian complexion makes it look like you are ALWAYS in dire need of a shower. At least I come CLEAN.

Well, I would make that one of the last resorts. I suspect there are easier ways to check that sensor. You can check the voltage as it sits now. If you'd like, I can get you the voltage range for the o2 (im sure its easily accessible online as well). If the voltage seems to high or too low, I suggest swapping it to bank 2 and making sure the code follows. Be sure to keep the non-foulers WITH the sensors they are currently installed with. If the problem follows to bank 2, then swap the non-foulers just as a precaution. Hell, it could even be something as simple as an exhaust leak now that I think about it. I'm just not used to diagnosing modified Z's.
I will have to do some reading to figure this stuff out. I didn't understand of what was being said in that thread I posted for you to read. I do have the 2006 350z FSM downloaded. I read through the section on cats and sensors yesterday but I don't know much about voltage.
