Can run in shop indefinitely without any codes

Runs great but seems rich
Checked STF and LTF trims and AF readings. 02 readings both sides appear very close to same numbers.

any ideas. Fuel pump is the next thing to change out. I have a Launch V431 Scanner

Have you changed so many things? Isn't that great?
Does the truck run good outside of the codes or does it have a miss or rough idle. It could be a bad/corroded connection or wire causing a false error.
Runs awesome. I switched out the bank 1 AF sensor and the P2195 went away for now but a P0420 code came up on bank 1 now. Reset it and waiting to see what happens. Hoping the cat will clean up. Thinking it is caused by the P2195 code.
