I have recently spent some time beneath the mysterious plastic cover
on the air box. I'm assuming the problem isn't just running lean
at idle, but running too lean all the time. Running too lean at
idle is more readily adjusted, I _think_ it's turning the adjusting
screw on the air box in a counter-clockwise (loosening) direction.
Someone correct me if I have that backwards.
If the problem is running lean all the time, and it's not a cracked
vacuum line or something like that, but a problem in how the FI is
adjusted, it's necessary to open the air box cover. On my '81 Westfalia
I turned the plastic geared wheel counterclockwise to lean, so I
presume you'll turn it clockwise to richen. I turned mine 8 clicks
of the geared wheel, and that was a very substantial difference.
I've never heard of vanagons with a problem of consistently running
lean, usually I hear of folks having problems running rich. The
list will hopefully give us some feedback on this, but I'd expect
the problem to be other than the FI adjustment, unless these
vans were adjusted for a high-altitude area at some point.
Good luck!
