A malfunctioning throttle position sensor will result in a decrease in engine performance, jerky acceleration and RPM fluctuations while driving.

Another problem that is frequently found in the i20s is a faulty transmission. The transmission is a complicated component that has many gears that interlock to transfer power from the engine to wheels. As time passes the friction between the gears can cause the transmission's failure. Sounds of grinding or clunking as well as rapid acceleration that is jerky are signs of a faulty gearbox.
