Hi all,
        Just wanted to post to the List my success in solving a vanagon "
challenge ". Actually, I would have saved a lot of work had I gone
immediately to Bentley and systematically gone through the fuel injection
checks. Instead, I relied on my fuzzy memory of the system and overlooked a
simple but necessary component. My van was stalling and stumbling at
takeoff but only after the van had been driven a while and was warmed up. I
switched the various FI components ( I have another van so I can do this )
Nothing changed so I suspected the throttle position switch was out of
adjustment, which I readjusted. At first this seemed to solve the problem
but the van only ran well when cold. So I continued to scratch my head and
ponder the possibilities, which as most vanagon caretakers know can be
numerous. I removed the engine cover for the umpteenth time and finally I
noticed the culprit. One of the wires on the power steering pressure switch
had broken, voila, problem solved after replacing  the push on connector.
Should have taken a minute and looked in the Bentley!
