Failure  to return to idle

Mordo, this problem can be caused by a number of  things some of which have
been mentioned by other postings.  You must  first find out if it's a me
chanical issue or a fuel injection operational  issue.  Removing the cable from the
throttle body and checking the cable  and throttle body operation for free
unrestricted movement would be the first  thing to do.  After that I would go
looking at the setting of the throttle  body idle control switch, the operation of
the ICV (idle control valve) and the  ICU (idle control unit).  Any and or
all of these items could be causing  this situation.  Now, if you find that the
throttle body is hanging up due  to the valve having worn a groove in the
throat, a very common occurrence, I can  offer you a rebuilt throttle body that
has been completely rebuilt and will not  wear that groove in the throat ever
again.  From my _Vanagon Used Parts_ (http://members.aol.com/Fkc43/usedpts.htm)
webpage -  Throttle body 1.9 or 2.1, rebuilt, excellent better that new
condition -  $250.00 exchange or $300.00 CND.  I do not currently have any 1.9's in
 stock so would need yours to rebuild.  Then if you find you need an ICV or
ICU I have those also, see my _Vanagon Items Forsale_
