What's the matter with the high idle speed of the accelerator after cleaning in Teana v6?

Reasons for high idle speed of throttle valve after cleaning of Teana v6;

(1) There will be impurities in the intake process, which will accumulate at the throttle valve for a long time, and the carbon deposition will be more and more after a long time.

(2) At the throttle, there will be resistance when reciprocating. If this situation persists for a long time, the engine computer will adjust the position of the accelerator pedal. That is to say, the position of carbon deposition is regarded as the ontology, that is to say, the throttle valve is not at all but near the position of carbon deposition.

(3) After the vehicle cleaned the intake valve, the flap still moved in the original formation, indicating that it was not in place, but the difference was that the carbon deposit was cleaned. So the air intake will be a little more than usual. This will lead to high idle speed. In this case, computer programming is required. If you don't do it, the engine computer will take a long time to adjust and recover.

The throttle is:

(1) The controllable valve is used to control the air to enter the engine, and after entering the intake pipe, it will be mixed with gasoline (different types of cars have different design mixing parts) to form a combustible mixture, which will participate in combustion and do work. Four-stroke gasoline engines are generally like this.

(2) Throttle is the most important component in the EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.

(3) Throttle is a controllable valve to control air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine.
