Ok, so.. last night I left the battery charger on by accident. However, this morning on the drive to work, I kept waiting for the car to start missing, and nothing.

So then today I drove it around some more.. battery is staying around 12.5V. Alternator output is 14v without load, 13.8 with load. I don't recall.. isn't charge supposed to stay around 14.5v?

I think this is a voltage issue. The problem kept coming and going. If I was in stop and go traffic, the car would slowly start missing. If I was getting all the green lights and in the higher revs, the car would return to normal.

Seems kind of strange though..
