Following some advice gotten from this group last week relative to an
erratic idle, I went to Bentleys  to find the throttle switch on my 85 1.9L
vanagon.  Looking at the engine, however, I couldn't find the throttle
switch--not the single or the double one.  How can this be?  The previous
owner about 90,000 miles ago had the engine replaced; I don't know if this
is an explanation or not.
