jerking when accelerating is a transmission problem. Well, i am pretty sure it is. It could be other things but the transmission is where you should start. could be an ignition problem, if it is shuttering at low rpm. Mine does this and i have a cylinder 2 misfire. This could be plugs and wires or, getting more expensive, coil pack or distributer problems.
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?
your car must be stuck in a low gear and not able to switch out
Sounds like it could be a dirty fuel filter, try taking it off and cleaning it.

Your A/C compressor is shot. It's internal computer (or that of your car) is malfunctioning. The "jerk" is when your "A/C" kicks in...an A/C compressor takes much of your cars usable power. As it turns on and off you will get the hiss and jerk. (the hiss comes from the overworked compressor lines cooling)
