Maybe you have 500# injectors in there. How is anybody going to answer your question without knowing how the car is setup?

Have you AutoTap it? Are you using the MAFT, if so what are your settings? Did it happen while you were spraying n2o?

Have you tried resetting the PCM and seeing if the code happens again? Maybe it was a one time thing... Thats weird that its running rich while you have the MAFT set to lean.
