Okay, I'm giving a long overdue update for this problem.   And AFAIK the
issue is solved.

I think I had already replaced the plugs/cap/rotor.    It ran okay for
about a week or 2 and
then the hesitation started again.   So I replaced the coil, and no dice.
Finally the plug/coil
wires were replaced and that finally did the trick.    To be honest, I have
no idea how old the
plug wires were but I guess they were done.    So I've driven a few weeks
with no hesitation
problems at all.

Thanks again for all who contributed.

Hi All,

The patient: 1990 Vanagon Camper
Stock 2.1 engine
Manual transmission

The symptoms:

   Hesitates just after shifting while accelerating.  Hesitates when
changing pressure up on the accelerator.   Release and it stops
hesitating.

It idles fine.   Revs fine with no load.

So I'm not sure what's going on here.
Fuel pump?
Fuel filter?
Ignition: just changed the plugs/cap/rotor.

I'm thinking it's time to change the spark plug wires too.

I just don't want to spend too much on guesswork.

Thanks for any and all suggestions.

Steven
