The tech found a spark plug with a broken ground electrode, and the plug was missing the washer / gasket (the interwebs informs me that the missing washer may have contributed to causation). Cylinder scoped out clean, swapped 4 plugs, and changed out the oil. A broken spark plug certainly wasn't the first thing I thought of when the car objected to my right foot.
Both plugs came out of the car, you can obviously see the one with the issue.
Also on the lucky-list:
Replaced top (broken strap thingie)
Replaced dash (bubbles)
AC compressor (broken shaft, also has to do all ac lines and condenser)

Several odd electrical issues at diff times (alarm, windows, AC, HUD, and etc, let's just leave it at several . . .)

With 93k miles when the spark plug failed, did you happen to find out when the suggested replacement time is? 100k miles?
