A malfunctioning throttle sensor could cause jerky acceleration, RPM fluctuations and decreased engine performance.

Another issue common to the i20s is the transmission that is defective. The transmission is a complicated component with many gears that work together to transfer power from the engine to the wheels. The friction between the gears cause wear and tear that can cause the transmission to fail. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of the gearbox being damaged.
