Check again -- any crack anywhere before or just after the primary O2 can and will cause this problem.
Apparently now the difference in fuel trim can bounce from one side to the other, so I think it has to be some kind of computer gremlin/glitch. They smoke tested the intake and exhaust and only found a small pinhole leak along the welds at the stock exhaust manifold where it mates to the TPs which shouldn't be enough to cause this....
