Sounds like your Vanagon has a case of Equine flu.
Very common this time of year.
The cure is normally a can of Techron FI cleaner or HEAT to get the moisture
out of your fuel system.

Subject: 2.1l: westy jumping around

hi list,

our westy develops a habit of jumping around unexpectedly. I mean that when
i want to accelerate from a stoplight, first nothing happens, it just starts
rolling forward slowly for the first 30 feet.
then suddenly there is a burst of power and it accelerates like crazy. it
doesnt alweays happen, just sometimes, you never know. usually rather the
engine is not warm yet, but not exclusively.
I have the upgraded air flow meter. i also observe that especially at higher
altitudes idle speed when cold can go down to 400, i dont know if thats
related.

I am very glad for any advice.
