Fuel issue?

93 5.0. Runs fine when I an not driving it hard. If I push it a bit, once I let off if sputters and backfires a bit once I give it gas. Any thoughts? It is also running rich. Could this mean that it is just getting to much fuel? Thanks for the help.

Clean the MAF, IAC & TB.
Follow the directions in your Chilton's or Haynes manual.
You could also have an exhaust leak before the O2 sensors.
