Pat,
things to look at according to the VW Vanagon Protraining manual for non-CAL
AFC ARE:
For poor idle, check:
Auxiliary Air regulator
Cylinder temp sensor
injectors
Exhaust gas recirculation
Deceleration air valve
Full Throttle Switch
Air flow Sensor
cold start valve

Poor performance, excessive fuel consumption:
Cylinder head temp sensor
fuel pressure regulator
air flow sensor
full throttle switch
exhaust gas recirculation
injectors
cold start valve
A vacuum leak anywhere in the system after the AFM will cause you to also
have a poor idle and high fuel consumption as well.
