Burnt valve, bad spark plug, bad spark plug wire.
yes but how can you tell if the coil pack is bad
Did you ever figure this out?
you can move the coil from that cylinder to another cylinder and see if the problem moves...that will tell you if its the coil.

Mostly a faulty spark plug or its connector is the problem.
Bad wire , spark plug or injector
Could also be a bad coil pack.
