Rev hang is conmon on modern cars and is due to emission controls. I suspect the cutting out is a different problem all together which may have made the rev hang worse due to the ecu trying to compensate for a faulty component by using a preset safety map. 02 readings like these dont mean much on there own. Go into live data and watch a graph of voltage of the 02 sensor/sensors to make sure thier reading correctly as the voltage should move around during driving.
