Why does my car Jerk when I put my foot down?

This is because the gas emissions caused by newly combusted fuel get backed up. When you put your foot down on the accelerator pedal, you are adding more fuel to the system and putting more pressure on the converter. The car will likely delay its response and then be followed by a sudden jerk or lunge forward.

Your catalytic converter have the function of regulating the emissions that come out of your car. At times, the rich mixtures of air and fuel flowing through your catalytic converter can clog up. This clogging stuff can lead to a jerking or stuttering motion when you press the gas pedal.
