Update
Turns out one of the coils had a gap due to a rubber spark plug socket breaking off down in the spark plug hole and keeping the coil from seating. I will never use those rubber sockets again, will use magnetic.
I replaced all coils and plugs with Ruthenium HX NGK plugs. Runs flawlessly. So for 24k miles the car intermittently missed on cylinder 3. I had swapped coils as I got a code, and have gotten random P codes for misfire, FINALLY FIXED!
