It is very cold around here now but I haven't experienced any "trembling" from the 2.0 engine. I even marvel at how smooth the engine is at all times. Now my wife experienced this once. She said when leaving work one day the car was very cold and she didn't warm it up. The first stop light she came to she said the car started to shake and it felt like it was going to stall. Since then she now uses her remote start when its real cold and hasn't had a problem since. Our car is garage kept and the only time its out in the cold for extended periods is at her work. Remember if you have a Turbo engine its a good idea to warm it up a bit before driving and in the Summer its a good idea to let it idle for a minute before turning it off.
