Are you hearing the backfiring or are you just feeling the "sputtering"?
Is it constant or is it random?
Did this just start recently or has it been an ongoing problem?
If it just started recently, did you get gas from a new place?
It may be moisture in your gas - maybe try adding a bottle of Heet (or some other moisture remover) and see if that helps?
