I have had a P0304 for months. Tried everything. Even replaced 2/2 O2 sensor, 2/1 sensor looked like it was replaced before awhile ago. Could be a sticky valve, causing 17% lower compression causing the cyl 4 missfire too. Someone replaced the 2/1 bank 2 upstream O2 sensor, and that fixed their P0304. Praise God if this works!!!
