What is the reason for the slow drop in Chery Bonus engine speed after the removal of the foot of the gas pedal?

The delay of a few seconds after the removal of the foot from the foot of the gas is a distinguishing sign of many of Chery Bonus, equipped with Euro3 and Euro 4 engines. The electronic engine data management unit uses an algorithm that increases gear shifting to achieve better performance.

However, if the backdrops are observed without a gearshift, this may be an indication of the failure of the throttle position sensor.
