Penetrating oil is fine to use.. just keep it off the new sensors and it will help if the car is warm.

Durametric reported the sensors (one on bank 1 and the other on cylinder 4-6. I looked at them both and one was totally swamped with oil which I cleaned out but think it might have done something. The other was molested by PO as the connecting wire is almost a foot long. I'm not kidding!
The o2 errors were there even before the MAF issue surfaced.
