LaCrosse throttle. I'm used to it. What happened when I was free?

This is because the throttle must be set after cleaning the throttle. If it is not set, there will be high idle speed and low idle speed. It is recommended to go to a 4S shop and let professionals decide. During the intake process, impurities will accumulate at the throttle for a long time. Over time, more and more carbon will be deposited. There will be resistance when the throttle moves back and forth.

Precautions:

If this happens for a long time, the engine computer will adjust the throttle position. That is to say, the position of carbon deposition is regarded as the car body, which means that the throttle is not at all, but near the position of carbon deposition.

After cleaning the intake valve of the vehicle, the flap is still moving according to the original shape, which means that it is not in place, and the difference is that the carbon deposit has been cleaned. Therefore, the air intake will be a little more than usual, resulting in high idle speed. In this case, if you need to set up a computer, it is recommended to go to the 4S store to make relevant settings. If it is not set, it may take a long time to stabilize.
