Your misfires are on cyls 1/3, which share a cam. You also mention a cam code. Might want to double check the timing.

It never hurts to check grounds for a clean connection.
I was thinking about it this morning, and the cam timing makes sense. Oil is colder and thicker and could take longer to move the cam into the right position, didn't happen when warm. Although I don't have the tools needed to fix it at home.
