My car has been putting out these codes consistently lately:

172 - Lack of Oxygen Sensor (HEGO) switches, indicates lean (RIGHT SIDE)

181 - Fuel system at rich adaptive limit at part throttle, system lean (RIGHT SIDE)

I assume the right side O2 sensor is going out right? Sounds like its constantly reading lean no matter how much fuel the computer dumps in. That would probably also explain my somewhat lousy fuel mileage lately.
