For those of you who have been struggling with the Vanagon cold-start
bucking. [Aproximately one to two minutes after starting, the moter will
momentarily bog and nothing except full thottle will save you.]

I've made two changes that have, for me, eliminated the problem. Since I
did both at the same time, I can't say for sure which did the trick.
The first was to replace the vacuum hose from the fuel pressure
regulator to the intake plenum. I found that while the hose looked fine,
it was infact so brittle at the intake manafold end it crumbled when I
pulled it off.

The second was to replace the idle stabilizer relay (behind the left
rear tail light.)

Hope that helps the people who have run into this problem
