@Travis801
Not likely in my opinion. Replacing the right bank (bank 1) front O2 sensor might not get rid of the code(s) either. I would check fuel pressure first. If it is on the low side, replace fuel filter, if that has not been done for a long while. Still low, suspect fuel pressure regulator, then possibly pump. imp
