Sounds like you might have a couple problems going.
It is possible that both symptoms are related.
If it were mine, based on the O@ codes you have, I would replace ALL of them. Not uncommon to have them all weak, but some only weak enough to set the code. Because they are compared to each other by the pcm, the next weakest one will set a code after the first offender was replaced.
This may resolve all of it. Certainly should for the second part.
If problem(s) are still present, I would be looking at these:
What is the fuel pressure?
Unplug the MAF and drive it, does it change the symptoms?
Pull the plugs and pay attention to what cylinders they came out of. Do they look normal?
Have you changed the fuel filter?
