Hello! My trucks been doing this weird stumble when I press the gas pedal. It sounds like it wants to choke out and die but then it starts to accelerate. And just now I was trying to accelerate when not only did it stumble, but I heard what sounded like a back fire coming from the engine compartment. What gives?
