How to repair the high idle speed of throttle after Nissan sunshine washing?

The reason for the high idle speed of Nissan Sunshine car after throttle cleaning is that the throttle opening of the car has not been reset.

The solution is: go to the 4S shop or repair shop in time to reset the throttle of the car to solve the problem of high idle speed. If it has not been solved, it is recommended to overhaul the idle system of the car.

Due to the long-term carbon deposition on the throttle, the carbon deposition squeezes the throttle, and the throttle opening also expands. When the throttle is cleaned, if it is not reset, the throttle opening will remain in the state before carbon deposition, which will lead to an increase in air intake, and in severe cases, the idling will be unstable and fuel consumption will increase.

Extended data:

Nissan Sunshine High Idle Speed is introduced as follows:

Most cars use electronic throttle, so it is necessary to use diagnostic instrument and computer to initialize the throttle in order to achieve normal idle speed. There are also some old models that use mechanical cable throttle, so these cars will gradually restore the throttle opening to the initial state in the future driving, and the idle speed will naturally stabilize.

Generally speaking, when the car is idling, the speed is very low, usually 800- 1000 rpm, and the gasoline consumed is definitely not as much as that during normal driving. If you want to consume gasoline per unit time, you don't burn much oil at idle speed, but the car is at rest at idle speed.
