Is my O2 sensor going south?

My A/F gauge is giving a relatively consistent lean run condition in all throttle positions. I start the car and the gauge reads stoichiometric and then quickly sweeps down to lean where it stays the remainder of the time.

Is my o2 sensor goin up?

That's just one of the many things it could be. You're going to have to go into a little more detail and do some troubleshooting to find out what the cause of that is. Is the car running normal at idle? Full throttle? Does it ping? ect ect.
