The problem is intermittent and although it happens daily, it doesn't
seem to happen for the mechanic. I guess the mechanic doesn't have
the time to drive the car around for a little while. I'm nearly
certain that no code showed up.

A suggestion was made to try Techron injector cleaner - should I try
that? I don't want to mess anything up. The car always eventually
starts..so far.

Thanks.
