How does Toyota Reiz solve the idling problem after cleaning the throttle and nozzle?

I ran a long distance the other day and found the car boring. When I arrived at my destination, I found that the belt was a little loud, but I didn't hear what it was. It's normal to drive in the city for two days, and it's a long way home. I feel good. When I stopped at the toll booth, I found that the car was shaking (N gear), the steering wheel and legs were leaning against the door, and the feeling under my ass was very obvious. I feel that the car is shaking even more, especially when the reverse gear does not give oil. The next morning, I went to the 4S shop (the car has been insured for a long time, 373 130 km) for inspection, and I didn't find out why. I suggested cleaning the throttle and injector, so I went out to clean it again. After cleaning the high idle speed, remove the battery negative electrode again. Some things are learned. After a day's cleaning, now it's idle. The above explanation, I hope a master can help my younger brother. Kneel down and thank you!
