after about 2 minutes of idling when first started, my 84 vanagon hunts bad.
(900-1100 rpm).  it runs well if you are giving it gas, but let it idle and
the hunting is there.  when i diconnect the plug on the air flow meter the
hunt goes away.
need an air flow meter, HUH?  i do not seem to be getting a nice steady
resistance reading as i manually open the flapper valve.  the bently manual
is not very clear.  it only states, resistance will vary when flapper moved.
i have cleaned grounds, fixed vacuum leaks,  had idle speed and co
adjustments all over the place, nothing truly helps.  oh yes the tune up was
done....
please help.
