What is the reason for the high idle speed of the newly changed throttle van?

This is a normal phenomenon. It will take some time for the new throttle computer to learn, and then the idle speed can be reduced to normal.

In the intake process, impurities will accumulate at the throttle for a long time, and the carbon deposition will increase after a long time. When the throttle moves back and forth, it will be resisted. 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 taken as the body, which means that the throttle is not in place at all, but close to the position of carbon deposition.

Therefore, the air intake will be a little more than usual, resulting in high idle speed. In this case, if you need to do computer settings, it is recommended to go to the 4S store to set the correlation. If it is not set, it may take a long time to stabilize.

Precautions for cleaning the throttle:

1. When the idle speed of the car is unstable, it may mean that the accelerator of the car needs cleaning. Some cars will also have external manifestations such as starting difficulties and even power decline.

2. Throttle is the mouthpiece for the normal operation of the whole automobile engine. Usually, 4S shops recommend cleaning cars when driving to about 20,000 kilometers. Of course, this kilometer is not very fixed. According to different models, some models can be eight or nine thousand kilometers.

3. The cleaning agent is very corrosive, and it is easy to cause excessive corrosion of aprons or oil seals during cleaning, resulting in unstable idle speed. Excessive cleaning of the throttle will also lead to premature scrapping of the throttle, and the throttle will not be broken because of dirt.
