After replacing the fuel filter I like to cut mine open and inspect it for
bits of crud. This can give you a feeling for how bad the problem is. I
have also noticed that there are two kinds of fuel filters available for our
air cooled vanagons; one looks like a small plastic cube and the other looks
like a metal cylinder. I have always used the plastic cubes, but I haven't
researched the relative merits of the two options.

I have a feeling it could be the fuel filter, I was imagining bits of junk
getting stuck when I was accelerating......so I'll change the filter,
another "first" for me, and hopefully this problem will go quietly away.
The van has run so good for over a year now!
I just had the distributor and coil replaced, my mechanic thought that could
be the problem, but it's still acting up.
I appreciate all of the advice given on this list, what would take me a week
takes you guys a couple of e-mails!

Hello there. You may want to type "vanagon syndrome"into the archives to
get some ideas. Sometimes it is difficult to determin if it is a fuel
problem or electrical problem.As for fuel, a clogged filter usually comes
with a whining sound attached.Low fuel pressure can be checked by pinching
the fuel return hose after the fuel pressure regulator. B sure to use a rag
w/your plyers here so the line is not damaged! Maybe a couple bottles of
your favorite, STRONG, fuel injector cleaner will do the trick.Clogged
injectors happen.Electrical problems could be the issue. First try
disconecting all the electrical connections in the
engine compartment and reattaching them(dont break any!). Maybe wiggle the
ignition key while this is happening. sometimes a worn out switch is the
cause.The dist. where the 3 wires connect with the hall generator is always
suspect.Inspect all the wiring for cracks or burns.This is a pain, and some
are difficult to reach.Maybe replace the old cap and wires for a check. Did
the problem happen after these were replaced? Did it happen after something
else was done for service?.Check the water temp sensor wire, as it can
easily be disconected by accident.What kind of gas mileage have you been
getting?Once again, the throttle switch is suspect. Listen closely as you
turn the throttle by hand. A quick click and then a click at full throttle
is supposed to happen.I think sometimes a worn out throttle shaft will make
the first click sometimes not happen.Gotta measure the gap between the idle
stop and throttle body. (.002-.004 WOW that is small!I think a piece of
notebook paper is this small. Try putting this in instead of a blade). I
once tried a stronger spring to close the throttle, but didnt work any
better. I think maybe a weaker spring will help this problem as the worn
shaft is binding more w/ a strong spring, and the weaker one will relax the
shaft a bit, and still close the throttle.Hopefully you will get this click
every time then. If you got extra parts , start swapping.Hope your problem
is ez to find.Jump starting is not good, and winter is coming. Good
luck,Roger
