AP1 Misfire Once Again
I would recommend reading the Misfire thread on here. There are a whole number of things that can cause misfires and that thread goes into a good amount of detail.
I've personally seen bad coil packs and injectors so it is possible that something else may have failed. See if you can substitute parts with a local?
That voltage malfunction sure is peculiar though.

I’ve replaced the spark plugs and coil packs 19k ago, I cleared the codes and driven 200 miles it has not come back on yet. When it does I’m going to replace the plugs and do a compression check while I’m there
Do you have a trickle charger you can put on the batt to insure its 100% when you go to start on these cold mornings? My first inclination as well, was that the coil packs just weren't getting full voltage at that particular start up and triggered the cel, but check one thing at a time, easiest first.
I have not checked the lash, or have done a valve adjustment on my own. I’m very comfortable on working on my own car, but leave the areas I’m not fully aware of how to do to InlinePro
Checking the valves is pretty easy, you may as well give it a shot now just to see.
Pulling the valve cover is a ten minute thing in these cars, then you just need the correct size feeler gauges with a 45* bend on them to do a very quick spot check for tight valves. (.008 / .010)
Compression test and leakdown test, man. That's where my misfire / idle rumble ended.

Had misfires... same type of codes..... replaced plugs, coil packs, etc....
Sent my injectors out for cleaning.... all came back good (supposedly)....
Misfire continued.
Borrowed a friends injectors (he's SC'd and doesn't use the OEM)....
Misfire is gone.... one of the injectors turned out to be bad. Replaced the injector for cylinder 2 after moving injectors around to find the bad one.
Still haven't figured out how I was getting misfire codes for all cylinders when only one was bad!
