Hi .

The P0320 is the crankshaft sensor .

O2 sensors on Bank one are both bad and need replacing ,all ways better to do all O2 sensors at the same time .

The crank shaft sensor will cause a you the misfires and bad running engine , this you said you replaced so now could be a bad connection on the sensor , bad wiring harness,or bad ECU .

This will have to be tested with the diagnostic tools ..

Do a exhaust back pressure on Bank 2 the side of the misfires .
