Been tracking down some codes that pop up occasionally on my '96 850. Was getting misfires but it looks like new plugs, wires, dist cap, rotor and a throttle body cleaning have taken care of those. The only one I still see is the P0172 (System too rich). Looking through the archives it seems to point to the O2 sensor. The car has 47K mi and has still has the original sensors. Most of the 47K mi is local so I'm guessing this might be a bit harder on the sensor. Any comments would be appreciated.

Tnx,
Dave
