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.

how many keys on your key ring? do you make sure the ignition is fully
in the "run" position after you start the engine or do you just release
the key? sometimes the ignition switches go, particularly under the
conditions i just asked about. if yours is on the way out, you'll have
intermittent running problems.

in the mean time, are you getting any engine codes? go to tegger.com
for info on how to read.
