it's hard to tell ......when stuble occurs as such you need to narrow it down to a system and without being able to examine ignition whenbreak down in rpm's occurs it's hard to make a guess and be correct

you need to find which cylinder is misfiring..while running pull plug wire with insolated pliers and see if spark jumps off wire on to plug to eliminate wire /cap issue....when pulling a wire you'll notice the engine load change= that cylinder is firing..when you pull one where you notice no load change..that will be the cylinder not contributing= pull plug and inspect..if okay perform a compression test on that cylinder/s
