Understanding fault code 850 1996

posted by  someone claiming to be bl on  Thu Oct 27 14:43 CST 2005 [RELATED]



Replaced to front O2 sensor and had two vacuum leaks fixed. One on the flame trap holder and the other in the rubber elbow down under the thermostat housing that you can hardly see. Are you seeing any black smoke or has your MPG slipped a little?

We don't have emission testing where I live (yet) but I believe this will cause you problems from what I've read here on the BB. Even if you clear the code & reset the MIL before going in, the test center can "read" the car's fault code history. Hopefully, someone who knows for sure will chime in.
