I think I can speak for the vanagons sold in 1990 -
1991. Yes, they had the hesitation problem as well.
After installing the titanium cap. The problem is
practically gone. I say "practically" because in
the Nevada high desert on I-80 I swear I could feel
it trying to hesitate and my wife did as well when
she was driving. Not as bad as it had before the
cap. fix, but it seemed like it was trying to. I
don't
know what it is about Nevada and my van but every time
I drove through there I'd have hesitation problems.
I drove all around the country 2 years ago and never
had it occur until I came back through Nevada again..
For those of you that have done the cap. fix and still
have problems, you need to check other possibilities
like the air intake boot from the air cleaner to the
throttle valve body. Mine was loose and gave a
similar
symptom. But there are other possibilities that give
the same symptoms I'm sure. Bad timing, vacuum leaks,
bad spark plugs, bad plug wires and many other ways
for this problem to rear it's ugly head. The specific
hesitation problem that the cap. fixes has to do with
the AFM picking up bad information from vibrations and
thus sending the mis-information to the control box.
This will eventually send the control box into a
default mode and the van will loose power but idle
fine. I've only experienced this on long trips of
two hours or more. If you are having this problem
occur in one hour or less, it's probably something
else. I would start with a tune-up and check all
wiring and go from there. If everything else failed
I'd start thinking about sending the control box to
Darrell Boeler to be exchanged/or repaired....
(Sorry Darrel, but you're still the best resource in
this area...)
My $.02...
