Hi Mike,
You are correct: when the EVC was last driven any substantial distance (back in November) it was basically running fine. ?Hence my complete surprise when it almost died on the way to get smog checked this week!
Today I measured the injector resistance, which involved unplugging the injector harness and moving some of the spark plug wires out of the way. ? After doing this, I'm now only getting a misfire on #6 (but it's still quite bad, with occasionally flashing CEL). The #2 misfire has gone away. ??
Did I fix the #2 misfire by messing with the spark plug wires? ? It's also less humid today. ?I'm still leaning towards coil pack or wires.
I've got parts on order and will report back as I continue diagnosis.

Mike,
You don't report a history of failure, because probably when you parked the EV there was no failure.? Please confirm this. The P0300 to me is a random misfire code, so that the ECU reports it and then tries to identify it to the cylinder.? IMO, you have to test drive a lot more.? Clear codes to see if the 3 and 6 cylinder codes reappear with regularity.? You're on the right track.? Your mileage does not indicate a mechanical failure, but that is possible.? You can use the fact that the motor is running to figure this out.
v/r,
Mike
