I took it to the dealer today and they said it was throwing a fuel pump code, but that unplugging those sensors did it. There's nothing going on with the fuel pump or AFM sensors since they're all in tact. The dealer said in order to get the check engine light off a tune would do it or to plug those sensor by in by having them welded onto the new exhaust. Tune it is! Thanks for the advice on it.
