When in a full stretch and when you hit the gas petal to go faster sometimes it makes the car jerk doesn't do it all the time but enough to be bothersome

This could be several things. I would start by checking if it needs a good tune up. Also, if that all looks good, make sure the fuel pump pressure is within the manufacturer's specs.
