Bad news is that no MAF and neither CPS have their own codes. The only way to make sure they are bad is to replace them.
The multiple misfiring codes are most of the time associated with bad MAF.
Those sensors don't last long on older models, so that would be my first thing to replace.
We don't know the mileage, but O2 sensors should be replaced at 100k mark, so if it is close to it, that needs to be replaced as well. Good luck
