Persistent trouble codes 850 1996

For some time now I have been experiencing the following symptoms:
- trouble codes P0133 and P0422
- poor fuel mileage
- a very subtle (barely noticeable) low frequency engine surge; so subtle as to not show up on either the vacuum guage or the tach, and evident primarily at moderate RPM (~2000), low road speed (10 - 15 MPH) and under a load such as climbing a grade.

MIL will remain off for anywhere from two days to a week. Ignition components and oxy sensor have been recently replaced. Car otherwise feels good, appropriate acceleration, etc.

Any clues would be greatly appreciated.
