How to deal with the plastic pipe falling into the throttle?

The tubes on the throttle valve of 1 are basically vacuum tubes, one is EGR (exhaust gas recirculation), the other is the brake vacuum drum vacuumizing, and the third is the cold car speeding up.

The working principle of electronic throttle is: the air intake is detected and controlled by computer through the sensor on the oil-gas pedal. If the pedal is stepped heavily, the throttle opening is large and the air intake is large, the computer will automatically adjust the corresponding fuel injection amount according to the parameters. The heavier the pedal, the more fuel is injected.

Not all automatic gears are electronic throttles, which depends on the vehicle configuration. The work of automatic gear is basically: P parking gear, R reverse gear, D automatic gear, and some cars also have S gear or L gear, all based on the configuration of gearbox. D gear, the engine generally has four gears, and some vehicles have five or six gears. After engaging the D gear, the computer will automatically jump from the first gear to the second gear, the third gear and the fourth gear according to the engine speed and kilometers. You must release the accelerator and step on it again, and the automatic gear will automatically jump up. If the car starts, you can hold down the accelerator so that you won't jump. Only when you feel the speed increase can you release the accelerator and then step on it, otherwise the computer will think that you are going uphill and will not shift gears automatically. The automatic transmission upstairs is infinitely variable, which is different from the automatic transmission.
