You probably have a bad o2 sensor or you need a real bad tune up.  If you can
adjust the mixture as someone recommended, then you definitely have a bad
sensor.  I would definitely not replace the air flow meter or the injectors.
Find someone that knows what they are doing.  BTW, why do people call a
Vanagon Air Flow sensor a "Mass Air Flow Sensor"?  They are not the same
device.

Try turning the screw on the air flow meter until it runs rough.  Get it
inspected, then turn it back till it runs right.

It didn't work for me.  Directions indicate you are supposed to add it
to a tank of gas, drive till almost gone, then test.  Made no difference
for me.
