  Need to know what those codes were. I'm betting they were o2 sensor codes, but please post the check engine codes.

  This is one of two problems : air/fuel mix or exhaust backing up due to fouled or plugged catalytic converter. You can clean your AIC motor at the butterfly and use electronic cleaner on your mass airflow sensor and see if this helps. Also, try a fuel system cleaner. If this doesn't help, I would be leaning toward a bad catalytic converter.
