I never found what was causing that problem you saw when I came by. It just disappeared as fast as it appeared (PFM).. I doubt it was anything with the O2s since it had issues in open and closed loop... but, the only things I changed were sealing up the exhaust alot better where the header collectors join up with the rest AND I put back in my interior kick panels and maybe bumped the brain box for the LTCC setup... hehe.. It just magically worked the next day after doing those two things and hasn't had that issue at all since. While Tony was tuning, I was having some voltage weirdness and the suspect is aging battery or alterntor regulator. Also, it was going crazy lean around 3-4k occasionally on some pulls and it wasn't able to be tuned out.... Again, suspecting voltage irregularities, possibly to Alt or Batt.. Taking them both to be checked soon.
