Mine hasn't done it since. From what I can tell, it threw the code when it was really cold out and now that it's warm, no codes.

Weird. My light will come on one day, turn off the next, and it’ll flash sometimes...

There is a possibility that your intake manifold is cracked. This was one of the main reasons for the misfire on the Coyote engine. I would have it checked first before looking elsewhere. Good luck!
