i would be looking at th egr valve maybe faulty or need a clean out ie carbon jammed it up remains open and when it should be shut at idle causing it to stall, a scan tool would help as you could watch the feedback change on the data.
if you let us know where you are im sure in this forum there is a mechanic from most states.

Carbon in the throttle body butterfly will cause all the faults you have including a o2 sensor fault. Take off the intake tube and douse a rag with petrol open the throttle fully and clean the area where the butterfly rests.
