Backfire in intake.....WHY?

Sometimes while im driving at around 30 and I hit the gas.....there is a backfire in the intake and I have no idea why. I dont know if it happens just around 30mph, I doubt it, but thats just how fast I seem to be goin everytime it happens....Anyone have any idea why?

Its a momentary leakout condition, to start check;

a faulty injector(s), leaking intake bellow, faulty fuel pump, plugged fuel filter, faulty/worn TPS. Also run some good injector cleaner through it.
