Once this was corrected I haven't had a problem.

AFR check is a bit more complicated because the test port is ahead of the cat and anything measured after the cat (lazy method) is not valid because the cat has already scrubbed the exhaust gases clean. The tailpipe is for smog tests only, not for tuning.
