I know this is over a year old, just wanted to update it for anyone actually using the search function.
Issue ended up being miswired O2 sensors and the upstream wideband sensor was in the J tubes. So finally there is closure to this... over a year later. I have pics in my journal on page 12. Also made a separate thread with pics posted as well. Sucks knowing I was all over it, but couldn't pin point the problem. Lesson learned. Thank you GTM for finding the problem
Also Megan370Z, you were right on the money, shout out to you on that. + rep
