New Mexico Roll Call.
A downstream o2 sensor is reading post cat so it saying that something is changing between the upstream and the cat. You could possibly have a clogged cat, a hole or your upstream o2 it reading a lean condition from which to dumping more gas in to comp for the 14.1 fuel/air mixture. But usually the MAS is what controls that. Id look for a possible bad cat and cracked exhaust manifold, loose intake/exhaust gasket. Or even a sensor unpluged. Unplug your downstream sensor and drive it around a see if anything changes it still the same prob just the sensor, but if gets even worse look a possible other stated items.
