Sounds Like a Mistiming Problem
One of the most common causes of any engine running rough is a mistiming problem where the engine is sputtering, backfiring, and/or just generally running rougher than what you are used to hearing.
Most of the time this is due to some broken or worn timing part, or stretching of the timing chain that results in the camshaft not being in sync with the crankshaft and thereby the valves are opening and closing at the wrong moments and the spark plugs are not firing exactly when they need to in alignment with the piston stroke.
