2.0T.
It has a rough idle and when you drive it, it kind of hesitates. Prior to this happening it didn't have any of these symptoms. It hadn't been started in a few days which was probably the cause of this.
I've been reading that it might be frozen gas lines anyone have any ideas?

 

I know this won't be of much help but I had the same issue a few days ago when I left the car sitting overnight in the cold (about -15 C). Mind you the car was just reving itself like crazy, would drop down to 500 RPM sound like it was going to stall, then rev up to 1500 RPM, and it did this for about 20 minutes. Next start was fine though, even after leaving it in the cold again.

At least your not on your own...

(I just noticed you are from Edmonton, and I was in Edmonton when this happened... Freaky! It wasnt on Sunday morning by any chance?)

 

Actually yeah it was on sunday! hahaha
craziness, I used some Fuel line anti freeze and it went away =D
