Radish,
1) I'd replace the Temp II sensor pronto. That'll prolly fix it.
2) If not, then I'd get a voltmeter and perform the diagnostic on the AFM.
3) Then, I'd prolly perform the "$1.98 capacitor fix" on the AFM wiring
harness.
There are other things it could be but those 3 are the most frequent it
seems. Get a Bently and work through the diagnostics regarding the FI
system. It's not hard.
BTW-Dealers are notorious "non-diagnostitions" regarding Vanagons. If they
can't plug it in and have the car tell them what to replace they don't have
a clue generally.
Cheers,
