Like Marc Perdue's description of his van's rain-related problems (from
around a week ago), your van's jolting/lurching, etc., sounds to me like
the same violent hesitating problem my 85 Westy had when I first got it
about 4 years back. First effective fix--following a maddening series of
costly misdiagnoses--was a wiring harness upgrade that VW recommended in a
tech bulletin aimed to address the "vanagon (hesitation) syndrome." Since
you're using a Golf engine, this problem may not be applicable, although I
wonder what original vanagon wiring may have survived the conversion and
whether or not the Golfs may have been susceptible to the same or similar
hesitating. The next effective fix to deal with the return of this violent
hesitating (2-3 years post-wiring harness upgrade) was an new oxygen
sensor. The latter hesitating problem was clearly associated with super
wet road conditions that were soaking my sensor and making it go haywire.
Might your van be suffering from one of the above?

checks out ok. The air flow meter has been swapped to three other good

floor it, then the lurching becomes violent to the point you think the
engine will rip loose from it's mounts.

it starts cutting out.
