Ok, there lies the issue.
I am sure you should have or will show 171,174 codes soon. These come from many possibilities.
Vacuum leak in the intake system
pcv valve bad, stuck open
mass air flow failed. Cleaning has little or no effect.
Low fuel pressure
the codes for the O2 sensors may be coming from the fact that they cannot control the fuel/air ratio with the trims so far out
