The performance of Geely Emgrand throttle failure, how to disassemble Emgrand throttle?

The accelerator of Geely Emgrand is dirty. When refueling, I feel that the throttle is stuck heavily, the speed is slow, the speed of idling on the throttle is slow, and the response is slow. When driving, release the throttle and the speed will drop immediately. Unclean throttle will affect the accuracy and smoothness of engine intake. One of the most obvious problems is that idling may cause jitter or even flameout, and the throttle speed is not smooth. Throttle disassembly method: 1 First, remove the air filter, unscrew the clamp on the throttle and take it off. 2. Pull out the pipe and put it away. You can see the throttle at this moment. Remove two screws and two nuts, and the throttle can be loosened.
