1995 Chevy G20 5.7 Hesitation + Loss of power?

My 1995 Chevy G20 5.7 (350 TBI) has been acting up for the past few months and been getting worse and worse.

The car idles fine, usually starts easily but sometimes requires light feathering of the gas pedal to start. When its in park, it revs up normally for the most part. when i put it into gear and add gas it seems to "bog." It loses power and i have to let off the gas or else it will stall. It also backfires from time to time if i gun it. I have changed the wires, plugs, ignition coil and nothing helped.

ideas?
