Easiest way is to start the engine and unplug each coil pack one at a time to see if the idle or engine sounds/acts different or the same. If different, that coil is good, plug it back in, if no change, that coil (or possibly the spark plug) is probably bad. Swap that to another position with a known good coil pack and retest. If it was the COP that was bad, the symptom will move to the new cylinder location.
