In a sense, I guess any problem that happens often to Vanagons could
be called "Vanagon Syndrome", but no, I suspect that this is not what's
wrong with yours. Unplug your O2 sensor. Just the single wire is all
that is necessary. Don't even need to open the lid if you don't mind
lying on the ground. Just follow the wires from the sensor, unplug at
the  connector.
    The problem that the harness repairs, needs a new name. Anyone have
a better name for Vanagon Syndrome? AFM temporary lockout, maybe?
