you can easily have only one side of a coilpack function normally, i just replaced one myself.

I would start with the coil pack, because you can basically test that for free. Swap it around with one of the other coils, and see if the problem follows that coil to the new location. If yes, it's the coil, and you need to replace it. If no, then it's most likely the ignition control module.
