I feel like a broken record with this same response of late but I don't mind
saying it again.

I had the exact same issue and I would check with your 02. You can simply
disconnect the 02 and it will remove the variable from the system to
eliminate its involvement. My 02 has less then 20K and failed again while I
have other cars with 270K that have never had them replaced!

No the fact you mention hills also can mean you are depressing the gas
considerably (in a vanagon of course he is!) which could bring the TPS in to
play as the cam can wear in these units. Once again bug me if you want a
digifant manual (86-91) to help troubleshoot especially if you mechanic
friend gets involved and he has no vw experience. The manual is well written
enough that any mechanic can test the systems.
