Can I throw my dart at the board? 1151 is for an intermittent oxygen sensor signal. That is not how the sensors fail. Look at the wiring harness for wires rubbed through, loose or corroded pins in connectors, or the harness fell down onto hot exhaust parts.
1132 refers to the internal heater circuit in an oxygen sensor; again, not how they typically fail. More common again to suspect a wire harness problem, especially when there's two related codes.
136 means the Engine Computer isn't happy with something about the driver's side oxygen sensor behind the catalytic converter. The best approach is to view live sensor data on a scanner to see what's being reported by the sensor.
The Engine Computer is doing it's job recording the fault codes so I'm not sure why you would replace that. Same with the fuel pump. That has nothing to do with these codes. The first two codes are for the oxygen sensors in front of the catalytic converters, not the back ones that you replaced.
The catalytic converters aren't the problem either. The job of the rear oxygen sensors is to monitor the converters' efficiency and set the appropriate fault code when one drops below a predetermined threshold. A problem with the converters won't stop the sensors from doing their job.
