seems to me the maf is failing causing you to run rich. Lock block 003 and 31 to see roughly what your afr is. What year is your car?

I can say that the o2 sensors are related to your maf problem. Both sensors wouldn't fail at the same time. I think you are just running very rich with the maf. Unplug it and see what happens.
