If we weren't talking about Vanagons, this response could be
considered a Friday joke.

70% chance it's an electrical fuel injection problem of which there are
about 27 likely causes.  Strongly recommend getting a Digitool from
Darrell Boehler.  I've been through about 8 of these causes and the Digitool
has transformed paranoia into serenity.
20% chance of fuel flow problems, about 10 likely causes, easier to
troubleshoot
5% chance of exhaust flow problem  about 3 likely causes, easier to
troubleshoot
5% something else, about 100 causes

Working with a dealer, you can easily roll through a LOT of money
shotgunning the problem.

Check the archives for some interesting bedtime reading by sending the

If that's not enough, try

You can actually search all the way back to 1994, but 1999 has covered
most of the  topics of interest.
