I just pulled these two codes from my 1997 850 T-5

P0133 02 SLOW 11 "O2 Sensor Circuit Slow Response (bank 1 sensor 1)"

and

P0172 RICH 1 "System too Rich Bank 1"


I've had an intermittent check engine light a few times now. Since resetting the light I've driven once without it coming back.


Can anyone help me with what steps I should take next ?

Which O2 Sensor is this ?

thanks !

P.S. I used Alex's software from: http://www.obd-2.com and I would really recommend it as you can also reset the Service and Check Engine light.
