Vibration from engine all of a sudden

Today I started up my 2007 Saab 9-3. It normally starts up right away with no problems. Today when it started the engine was running very rough and had a lot of vibrations. After abuot 10 seconds the RPM died down and the engine eventually quit. I started it up again to find the same vibration. I thought that if I let it run for a couple minutes things may warm up (-10C outside) and the vibration may go away. No such luck. When I put the car in gear (automatic transmission) it felt like the vibration got 3x worse. Putting the car in neutral eased the vibration. Needless to say I didn't drive it anywhere and just left it.

Anyone with any thoughts on what this might be?

sounds like its misfiring, as said above it could be a coil pack or a burnt out spark plug. best thing is to get someone to look at it to save damaging it further!
