It is a result of the air to fuel mix , when the intake is cold the fuel doesn't vaporize as well causing uneven fuel delivery to the cylinders. Once the intake and system warm up it should normalise, but most newer vehicles have a pre-heat device to keep this from happening, if this is a newer vehicle , you might want to have it checked.

What kind of car is is? When it jerk while shutting off, do you turn the key off and it sits there chugging for a second before stopping?
There are several problems that could cause your car to jerk when slowing down. The most common cause would be a transmission problem.
It jerks because the gas tank is on the left side. When the tank isn't tightly screwed on it may hit the inside parts of the car causing it to jerk.
