Hey, all you guys are great! Thanks so much for all the input and ideas. Here is an update:

It was 20 degrees overnight here, so I secretly left the car at the dealer yesterday evening and showed up unannounced this morning requesting they sit with me when I start the car after sitting all night. It worked like a charm. Two technicians stood outside the car, I started it, waited, gently pressed the gas pedal and "The Jalopy Syndrome" kicked in. Sounded like an old Model T or something. Their response was, "Ohhh! Okay!"

I mentioned to them some of the issues you guys were having and what remedies you found. They nodded and said, "Could be that, we'll have to check. Might be software. Might be intake manifold." Etc. Etc. But it was like a light went on in their heads.

Appointment on the 8th of January to check this and a few other things. I have a full list of SIB's, remedies, suggestions, etc., as well as some of your responses saying your cars didn't have this problem in colder temperatures - all in a bulleted Word Document titled RESEARCH. Hopefully they'll see I'm not going to go away!

Again thanks to you all! I WILL update after the appointment.
