codes po171 and 174 code help.

Hey guys, just did a bunch of work on this car including plugs VC gasket, oil filter housing gasket, and thermostat. Ran for about 30 minutes and than drove 15 miles. CE light popped on and these were the codes. Bank one sensor 2 is trim is reading in the red at 99.06. The others are reading in the green. Do you think this is related to any of the work I did or is it actually a bad 02 sensor?



Thanks for any help
