Instructions for adjusting the AFM on a VW bus, but also of interest to

Wedgies with EFI...

I like his approach of asking what the engine wants.

The pictures are really cool too.

Good article. However that's adjusting by ear, you have to have a very trained

ear to hear subtle changes in the way and engine sounds. The best way would be

with a wideband O2 and a vacuum gauge.
