Hi Ken,

I had the same problem last year.  On the good advice of our list-members,
I cleaned  the track of the AFM meter, installed the cheap "capacitor"  fix,
and since I was replacing the collector pipe, replaced the O2 sensor as
well.  I did these 3 things without testing which individual "fix" caused
the bucking to stop.  The van has been running beautifully ever since, not a
hiccup for a year and a half now.  (Fahrvergnuegen!)
There is a lot of information in the archives on how to do these fixes.
Of course, something else may cause your bucking.  What I did was cheap and
might be worth a try.
