bad coil pack?

Is there a way to find out if you have a bad coil pack?

normally a bad coil will throw a SES light for misfire on a specific cylinder. then you can swap the coil pack with another cylinder. If the problem go to the new cylinder then you know you have a bad coil pack. If the problem stays in the same cylinder it could a bad plug , a bad wire or both.
