intake backfire

i got a wild question?? is there a possibility that a intake valve was left open and that's why it's backfiring?? also, could a throttle position sensor or a coil or a MAP sensor cause this?

We already did that, We also put new: Plugs, Wires, Cap, Rotor and we changed the EGR Valve and the alternator.
