Sorry about the delayed response. The delay is because I got a new iMac
and my NewsWatcher program will not run under the Mavericks OS X 10.9.
I am booted to an old backup drive to be able to access the newsgroups.

I fixed the 01 C5 problems by trading for a pristine 08 Black C6. It is
awesome and this one has a GMPP warranty for three years and 36K miles
on top of the 18k on the car.

Dad, I have appreciated your help and I think you have my email address.
