I don't know about the Maser specific misfire codes, but I know here in Minnesota, if you've had a BMW, VW, Audi, or any other car with fairly high compression, if the car misfires once on a cold January morning, the check engine light is coming on, and its a random misfire code. Re-start the car a few times, drive it for a bit, and the light turns off. (that doesn't mean there isn't a huge line at all of the above said dealerships a few times per winter)
I think modern knock \ misfire sensors + the tendency towards higher compression motors means this is going to happen more often. It's basically just the first cylinder that fires on start happens to half-fire and then the motor lights.
