Good start on the typical items. Two things more that you can check:
- Is it your CAI that is causing the misfire/rich condition? Most of them can give problems like that
- Compression test, coolant test for combustion gasses, and oil test for coolant.

He didn't say what brand, so I was leaving it open as an option it could be. Some crappy intakes out there.

Hmm
Rich will foul plugs. Fouled plugs will cause misfire... Vacuum leak will make it run lean, not rich.
Dirty injector that is not closing? Run a can of injector cleaner through the tank? I like Lucas, but it depends on what they have where you are.
20 petal stomp after all the work you did?

Driving my unreliable rx8
I'm thinking it's the 02 Sensor. If everything was running right I would not suspect the CAI.
Try unplugging the Front 02/lambda Sensor and seeing how it runs.

I had the same P0172 code and discovered that the nipple on the throttle body that's supposed to be plugged when a CAI is installed wasn't plugged. The plug had come off somehow. (Maybe I did it when I changed the plug wires.)
Also, smell the oil on your dipstick. Does it smell of gasoline? If so, you should do an oil change.
