So I had the exact same problem with week with my truck. Idled fine, if I press the gas pedal slowly it would rev just fine. If I pressed it quickly it would sputter and backfire and other general weirdness. I swapped in a new high pressure fuel pump (inline not the one in the tank) and it runs like a sewing machine.
