And, a potential engine misfire, if it's constant, will have way more of an effect at much lower speeds when the vehicle is just starting to accelerate. That's when the engine is laboring to get the massive weight moving. And the misfiring cylinder would be fore easily felt. But, as the speed increases, the individual firing effects of all the normally operating cylinders, will mask the one cylinder that is misfiring due to the fact that you'd not miss the missing power from an individual cylinder other than a bit loss of power.

I was trying to figure out how to express this concept but eventually decided to wait and see if someone else captured it. You did. Misfires almost always "disappear" at higher RPMs. They're still there, but less noticeable.
