Thanks for the input guys. I got back from the shop last week just before I drove 1000 miles to and from Colorado.

Turns out there was a large hole in the intake causing a huge vacuum resulting in the cylinders misfiring. They also replaced the coolant censor sense that was faulty.

Everything seems to be running fine now, started cold no problem at 9°F. Though, they did say Martin, that I may need to replace my coils, if that didn't help.

They also suggested a Timing Belt change, especially with my car approaching 100K miles. Which I have read about being a problem.
