Jerk while starting to Move

I purchased a '01 Galant from a dealer recently with 79k miles on it. From a couple of days, i am noticing that when the car just starts moving forward there is a jerk.....any one knowz why this occurs.

Is it an engine miss, or gearbox related? If just an engine miss, a tune-up might be in order.

it might just be you fireing order with your plugs call like autozone and ask them for the fireing order and check it with the dirstubiter cap and the wires
