Other than a possible miss, what are the symptoms of a bad coil pack and how can you test them?

Coil packs pretty much work or they don't work. They don't get weaker with age or use. When they get very hot they can go open.

With the engine running, use a timing gun to test each spark plug cable.

How old are your valvesprings?

My car started breaking up and it was too late, lifters and cam were toast from bouncing weak springs.
