A few misfires isn't (shouldn't) gonna break anything. I've plain old unplugged the fuel intector signal wires while testing my motor for issues. Car idles like a pile, but it's not gonna break the motor unless you go out and romp on it, and even then as long as it's not detonating, it's not the end of the world.
It actually may be something as simple as a loose connection on the spark plug or fuel injector... any chance you bumped anything while working on the intake?
