Hello All,

I have a 1996 850 with 200,000 on it and it is a manual. The "Check Engine" light just came one. The car runs fine. No change in the idle or performance. I'm sure, based upon prior experience, one of the oxygen sensors has gone. My independent shop replaces both at the same time. This is based upon their experience that once one sensor fails, the other usually follows suit.

This is nearly an $800 repair, which I can ill afford. I have purchased the open wrench that iPd sells to remove the oxygen sensor, but have never undertaken this repair. Can anyone direct me to a source that provides good details together with pictures to show how to remove both sensors?

Thanks to all who reply. I'd really like to be able to make this repair on my own. I'm tired of coughing up that kind of money. I have another 850 the same year, plus a '99 XC and they too have had their oxygen sensors go.


Thanks!

Hugh
