1986 VW Vanagon: losing power..warmed..50 miles..lost power..40-45 mph

Resolved Question:

We recently purchased a 1986 VW Vanagon (perhaps our first mistake) After searching on line for info. it appears to be a common problem of 80's Vanagon's, is a significant problem with the engine losing power while driving after the engine has warmed up. For example: we picked up the vehicle and drove for home. It drove fine for 50 miles when all of a sudden the engine lost power (not died) and the speed dropped from 70 to 40-45 mph. This situation can happen after 10 minutes of driving or after 45 minutes of driving. In a minute or so the engine regains power and we can return to "normal" speed only to have it happen again in a very short space of time. It has been suggested it is related to fuel injection and that VW put out a missive regarding it many years ago...however, no one seems to know what to do to fix the problem. Help!!! ?

Hi, my name is XXXXX XXXXX is common onthese, the mass air flow sensor get a vibration from the engine, and after 1/2 hour top 2 hours it will cause this problem, VW has come up with a converter to install in the connector at the airflow meter, this will correct this problem, the part number of this converter is 025 906 302 A, you can get this from your local VW dealer,Tim
