I don't know, but it's caused by a too tight accelerator cable. Not the
cable under tension but the housing under compression.

The freeplay in the cable prevents the throttle from being moved when the
engine flops around. It's your classic case of "feedback".  Maybe there's an
adjustment to back off the cable housing to give the engine more wiggle
room.

Even worse is when this happens on clutch cables, not a problem for Vanagon.
