I have a not-so-much-annoying-but still puzzling issue with my 90 Carat,
2.1l wbx with AT:

It generally idles a bit high - at about 1000rpm. I haven't gotten around to
adjusting it down. But, when I put the trans in neutral or in park, the
engine is turning at about1600-1700 rpm. If I tap the accelerator pedal, it
will drop back down to its typical 1k rpm idle. When I come to a stop at a
light or stop sign, the engine pushes hard against the brake and the idle
holds at about 1100 rpm.

The pedal requires above-average pressure to hold speed while highway
cruising but does not otherwise seem unreasonably stiff for a linkage that
runs such a long distance. I've never driven another Vanagon enough to know
what normal feels like.

Engine idles and runs well, good acceleration, easy cold start, easy hot
start.

So, do we think the problem lies with the mechanical linkage anywhere from
pedal to throttle body or do we think vacuum-related or do we think
something else entirely?
