Correct the vacuum leak at the map sensor and it may correct itself.If you have the plastic vacuum lines check very closely for cracks.Also check wiring at map sensor.Delete codes by disconnecting the battery for a couple of minutes.

If you have a vacuum leak, you get a lean condition, not a rich condition. If an O2 sensor is bad, you may get a lean or rich code, but normally you get an electrical fault code. It is rare to get a lean or rich code from an O2 sensor when the sensor is at fault, but not unheard of.

If you have a vacuum leak, the O2 sensor should pick it up and richen the mixture. But there is a limit and it can only go so far.
