throttle valve This information is passed to the control unit and is used to the calculation of the amount of fuel needed A malfunctioning throttle sensor can cause jerky acceleration, RPM fluctuations and decreased engine performance Transmission problems are another common problem in i20s The transmission is a complex part that has a lot of gears which mesh together to transfer power from the engine The friction between the gears leads to wear over time which can cause the transmission to fail The signs of a damaged transmission include clunking or grinding sounds and rapid acceleration that is jerky Spark plugs are a different area of concern for the i20 Spark plugs that are defective can cause damage to the engine because they do not deliver the correct amounts of sparks to the cylinders A damaged spark plug could cause expensive and serious engine damage if it is not checked
