Check Engine Light/Codes 2099 and 2097
 
This morning I went to visit my dad, and when I started the car the check engine light stayed on. I went to Auto Zone and they pulled 4 codes: Post Catalyst Fuel System Trim Too Rich 2099 X3 (bank 2) and Post Catalyst Fuel Trim System Too Rich 2097 (bank 1).

The car is running awesome and I took it for a quick sprint on the highway (nothing crazy, only went to 65 mph and didn't redline it). No issues.

Does anyone have any ideas on how to remedy this?

Have you made any changes recently to the intake or intake filter?

:redface: I *might* have run a can of Sea Foam through the throttle body 3 days ago ... but I've driven the car a few hundred miles since then and the CEL just came on when I started it this morning :redface:
