A damaged throttle sensor can result in abrupt acceleration, erratic RPM changes and reduced engine performance.

Transmission problems are a common issue in i20s. The transmission is a complicated component with many gears that mesh together to transfer power from the engine to wheels. In time the friction between the gears can lead to the transmission's failure. Grinding or clunking sounds and the jerky acceleration can be signs of an inefficient gearbox.
