O2 sensors 850

posted by  someone claiming to be NJA on  Fri May 21 13:10 CST 2004 [RELATED]

Long story, but I am in CO and I'm flying back to Chicago to pick up my '94 855 Turbo. Before the car went to Chicago, the check engine light was on, and I had the codes read, and they were:
1. O2 sensor
2. running rich and
3. knock sensor(?)

Not too worried about the 3rd, hoping it'll go away if the O2 sensor is replaced...I'm pretty sure the "running rich" will for sure. My Q is: I forgot if it was the front or rear O2 sensor. I want to order the part from Groton before I go home....which is the sensor that usually goes first...car has 92k and I can't check the codes from here. Not looking for a definitive response here, I know it COULD be either, but which one (front or rear) do you folks think it is that has gone bad? Maybe the other codes will give you mechanically inclined folks some idea if it's the front or rear...

Thanks,
-Nick
