A couple of weeks ago, I posted a few messages concerning problems
accelerating at green lights when engine is hot and particularly after
longer waiting time period at the light . My mechanic look at everything
suggested by the list (from timing to O2 sensor and even cleaned all
grounds ) but the van would still misbehave ( no power).

He finally found the culprit : the 35 volts 22 microfarad tantalum
capacitor installed in the airflow meter harness ( the original
capacitor is a 10 volts but on my van I had replaced the 10 volts with a
35 volts)

My van is equipped with the modified air-flow meter harness which solves
misfire in the vanagon after extended highway driving. But for some
reasons, I had replaced the 10 volts tantalum capacitor found in the
harness by a 35 Volts tantalum capacitor because I still could feel
hesitations from the engine, at times, on highway with the 10 volts. I
was told that the 22 microfarad 35 v. (there were no 25 volts available
which is the one suggested by many listees) could simply handle more
resistance and would work fine. Well it did not. After cutting one of
the leg of the capacitor, the van ran perfectly and still does since
then. It actually never runnned better. So I went to my electronic shop
and bought the supposedly correct part, that is a 25 volts 22
micro.capacitor, which I planned to solder back in place of the 35
volts. Hope this will help the fellow who posted a similar problem with
his van recently.

 I still don't quite understand though why the 35 volts didn't work.
What is the problem with being able to handle more resonnance or
resistance ?

 Maybe Tim knows... Thank you so  much.
