...you had right side O2 sensor issues.
I'd expect O2 sensor issues to contribute to stumbling before oil pressure, unless the engine is trying to seize, of course. Might be low idle/stalling is causing oil fluctuation, but for now I'd not focus on that as a primary issue. Work it later. There is no code for fluctuating/low oil pressure.,,,the EEC doesn't include it in any of it's strategies AFAIK.
If you don't know the history of the O2 sensors, it might be time to throw fresh ones at it. Sanity check the harnesses first, then pull the right one and inspect. If you do replace them, be sure to research the correct part number, and pls. don't buy cheap...you want fast response, not lazy.
Remind me...no cats, right?
