Hello, 1, high idle speed after washing the throttle: this needs to match the throttle, and all brands of cars are different. Some need computer adjustment, some cut off the power supply, step on the accelerator and turn on the key switch. Specifically, you need to Baidu yourself according to your model. 2.
