The electronic throttle is dirty. What happened to the vehicle?

The most obvious is the power of the engine. When the idle speed of the vehicle is unstable, it is difficult to start, and the power drops, it means that the automobile throttle may need to be cleaned. Precautions for Throttle: It should be noted that the throttle opening should be reset after the throttle is cleaned, otherwise the automobile computer has memorized the opening when there is carbon deposit. If it is not reset, the engine will have unstable idle speed and high speed, which is worse than before cleaning. Different models have different reset methods, which will not be introduced here. If the owner has concerns, it is best to go to a professional repair shop or 4s shop for maintenance.
