When I read the title the first time I was
reminded of the Adams Family.
Then I remembered how I was plagued with lurching
on a roadtrip to the East coast in 1997.
In my case, it was a bad airflow meter.
Just one more thing to consider .
Bucking as it is commonly called. 3,000 miles of
it!!
And when I got home, I joined the Vanagon list
and you gave me the answer to this .
I replaced the AFM and added the capacitor
harness.
