I pulled the Cylinder Head Cover, and took a peak at the chamber for #1. You can see lots of corrosion down there:

The other 3 Coils and chambers (unsure what the official name is) are spotless
Thoughts on what caused the rust and sludge? Perhaps a bad seal at the spark plug, allowing some air/fuel mixture into the chamber?
I'm taking it to a dealer in the next couple of weeks for some un-related and relatively minor warranty issues, and I'll be adding this one to the list.
