2771 Oxygen sensor dynamic diagnosis before catalytic converter, bank 1
2772 Oxygen sensor dynamic diagnosis before catalytic converter, bank 2 This is usually bad O2 sensors. But, it's rare that both go at the same time. I've replaced 3 of them now on the drivers side since I went catless. I would switch them or get a new one and see if it fixes the errors.

This is probably failing primary cats. I would replace the low pressure fuel sensor, clear the codes and then see those two return again before doing anything else.
