Truck wants to die when I hit the gas


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.
 
I went and bought a MAF sensor, turned the truck on, and.....big difference. I can rev it up and everything I just drove it around. if i really whomp on the throttle and let go it will still backfire but it runs and drives thanks a million to everyone who posted on here to help me.
"Art" I believe you can clean your MAF sensor wires with electrical cleaner.I would have tried that before buying new MAF. But you got it working.I know that K&N filters that get over oiled can dirty a MAF sensor.
