backfiring through throttle body

I have a 1992 Chevy Astro Van with a 4.3. The problem is when i step on gas pedal it back fires. (it falls on its face) I recently replaced my distributer cap, rotor, and distributer in aug. I only replaced that because it was wore out. This made not difference. it still falls on its face.

Help me please
thanks in advanced

The other day the van died going down the road. I replaced the plug wires, distributor cap, rotor, and modular. My van runs now and good
