More than likely you have a vacuum leak, a loose mass air tube, or a faulty mass airflow meter. The codes were p0171 and p0174?

The clamps on the tube that goes from the mass airflow meter to your throttle body might be loose.
Make sure that you don't hear any unusual hissing noise at idle, make sure that all of the vacuum lines are connected to the intake and anywhere else they run.
Have you done any modifications lately? If so, retrace your steps and make sure that everything that you may have disconnected is reconnected.
