If only one bank is indicated, there may be an air leak in one runner to one or more cylinders. This becomes unmetered air into the engine
Look for a gasket falure for that bank, a crack or some other reason air might be getting in.
The again it could be a OX sensor that has given up.
Usually a lean condition that affects all cylinders will show both banks to be "TRIMMED RICH" in an attempt to correct a lean condition.
