rough starts

[roccit_53 at scirocco.cs.uoguelph.ca (C Boyko)]

I was thinking mine (the 87 16V) had a bad ignition switch or a bad ground
in its latest round of bad starting, but it was in fact an issue internal
to the starter itself. If you have access to a spare one, that may be
something else to try out.
