You have a rich mixture, O2 sensors ALWAYS fail lean (low, no voltage signal), the normal voltage from an O2 sensor in a system running in closed fuel loop will be varing up and down, lean, rich and so on the PCM uses the O2 output to always trying to maintain a 14.7 to 1 fuel to air ratio. Why did you replace the O2's?
