Stop in for a cup of coffee

Cold and rain. Lots of rain.
This is not helping my weekend plans at all.
F250 with a 6.2,did service on it, fire it up and hear a nasty snapping noise. Spark jumping out of one coil. But no misfire.
2 plugs per cyl i guess. Looks like a real act to get coils off.
Pitter patter...
Coffee first.
