Hello Troops:  While sitting at a stoplight the other day, I was
repeatedly pumping the brake pedal(for lack of any pretty girls to
ogle at on either side of the Vanagon) and the idle increased about
6=700 rpm before returning to normal.  I realize I may have been
screwing up the vacuum supply/demand chain there, but is this
something indicating a repair down the road, or do I just have a leak
somewhere that needs attention?  My VDO vacuum gauge on the dash
shows no change while I do this.

Thanks
