Default Code problems P0150,P0174, P0159, P1174

My wife’s disco has been giving us fits lately. Codes so far have been

P0150
P0174
P0159
P1174

I have replaced the bank 2 upstream oxygen sensor with a new Bosch. I also have replaced the mass airflow sensor with a junk yard unit.

The truck is still pissed.

And the search fu isn’t working. What do I need to do now?

Update. Swapped out the MAF from my disco to hers. The thing is still throwing codes. So not the MAF.
