Replaced MAF, Check engine light ON

Those two codes could mean vacuum leaks since they are reporting both banks. Lean conditions. Highly unlikely that 2 O2 sensors could go out. I would reinvestigate the Maf, maybe clean and be absolute its fastened well.

I have watched several videos on replacing the oxygen sensors. The car is 18 years old and the code says oxygen sensors. How long do oxygen sensors last?
