[s-cars] POS testing procedure

I've narrowed the misfire that manifested itself yesterday to cylinder #2 via pulling the injector lead and having no change in poor running. This morning, the issue was not evident on the trip to school with the kids until about 10 minutes into the drive, at which time it was a total lack of fire on that cylinder, so I'm guessing it's heat related?  Back home now and need to isolate to coil or POS channel after I pull the cover to make sure it's not a plug, (the heat issue leads me to believe that's not likely).  Forgive me if this seems like a ridiculously simple question but I have a PM brain on technical staff and he hasn't shown up yet.  AM brain is not at all a viable alternative, especially this morning for some reason....maybe he has evacuated in preparation for Earl making landfall tonight.... anyhooo, what's the easiest procedure here? Pull the coil cover and swap two coils to see if the miss moves, or swap the POS plugs?  The plug leads from the harness to the POS's aren't long enough to just swap them from one to the other, so I guess I'd have to remove the POSs from their respective brackets and switch them?
Really, I'm not this stupid, but damned if I don't feel like it this morning....

Lil help?

Thanks...
