Cleaning an O2 sensor for P0133 850 1995

http://www.volvo-forums.com/index.php?showtopic=19099&hl=o2+sensor

You can move the rear O2 sensor out of the stream, but not the front. Check the wires and look for non-bosh garbage sensor. Also check the elbows for the fuel pressure regulator vacuum line at the fuel rail, any leaks and you will be running rich.
