Hi Bob,

Are you saying that if you are setting you timing and the timing lite shows
the timing flutting around by a few degrees it's a result of a bad idle
switch.  Should the timing be rock solid at idle?  I have an '84 Automatic
(Digijet).  I'm trying to work out a slightly rough idle after the van has
warmed up.

Thanks in advance
