My 85 Vanagon is running rich--the exhause smells about usual but is
much stronger than normal.  While stopped at red lights, the fumes are
bad.

To correct other problems, I have replaced the digijet, plugs, wires,
rotor, cap.

My mechanic's answer is to try higher grade gasoline.

A friend suggested to replace the O2 sensor before heading to the VW
dealer.

Any help is appreciated.
