If any of your vacuum hoses or slightly cracked or worn, now is a good time
to replace them and perform another vacuum check to make sure there aren't
any more vacuum leaks.

Connect a tach to the engine while disconnecting the wires one at a time.
Note the specific drop in RPMs.  Sometimes it may seem like the RPMs change
but with a rough idle, you need to know for certain.  Take the wires off one
at a time and then replace them two or three times and all.  Verify that any
changes in RPM are specific to THAT cylinder and not because of a rough
idle.

Sorry, but Sanity and 35 year old Volkswagens do not mix well together.  You
may want to review your head for leaks before driving your VW again. (uh,
your real head, not those on the engine).
