I got a 99 dodge 2500 has problems getting it to run right seemed like misfiring would buck when hardly touched gas and now I've replaced everything to so with that and it back fires when cold can't figure it out when I let to of gas back fires now

Is there gas in ur oil? If there is it could b a stuck valve, and that can also lead to it backfiring.

And it could also b an oxygen sensor
