I have a slight jerking in the car when I lift my foot off the gas pedal and the car slows down, then when I press the pedal again there is a slight but noticeable hesitation.
Might just need a throttle clean, every lancer ive driven does the exact same thing. Its just the car. If you have a throttle controller it makes it much more noticeable just because of the level of throttle thats being applied when you touch the accelerator. You shouldn't have any problems though.
After I press the gas pedal, the car drops the RPM to 1,500 or lower and stays there on its own; the only thing that helps is pressing the gas pedal hard again.
