White Smoke

[Drag0na5h]

I usually drive my car daily so I rarely have this problem, but today I started it up after not driving it for about two days and it had a very hard time starting. But as soon as it did fire up nice, I looked out my passenger side window and saw a BIG cloud of white smoke fly by (a bit windy today). I find this problem occuring at random times, but usually the smoke isn't that bad and it's always white smoke. After I noticed this problem occuring I also noticed the difficulty in starting the car itself. Another thing that may help explain is that after the car is started and I add a little gas, it wants to choke and die. Most of the time I save it by reving the engine up a little higher than idle, but it wants to die sometimes even after that. Timing perhaps?
