Describe 'kicked'? Doesn't that hurt your foot? Is it warming up properly , or is it taking longer than usual?
when the ignition is turned on it starts normally but once you step on the accelerator the engine begins to jerk but becomes normally after 10 minutes when the engine has warmed up. If the car has been running this usually does not happen unless the engine cools down completely. what do you feelis wrong with the car.

Possible faulty coolant temp. sensor? Can be tested.
