Can't the car start after cleaning the throttle?

Recently, everyone is concerned about "can't the car start after cleaning the throttle?" The relevant content is explained as follows. The reasons why the car can't start after cleaning the throttle are as follows:

1. If there is too much sludge in the throttle, the engine may accelerate slowly and the fuel consumption may increase. As long as you clean it, you can buy it in a 4S shop soon. In fact, you don't have to, you can get it yourself, just don't forget to initialize it;

2. When cleaning the throttle valve, first remove the intake throat, expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle valve, and then carefully scrub it with a polyester rag or a high-spin "non-woven fabric". Deep in the throttle, you can hold a rag and scrub it carefully where your hands can't reach it.

3. After cleaning, initialize the throttle according to the disassembly procedure just now. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, because there was sludge blockage before. In order to ensure the air intake, the computer will automatically adjust the throttle opening to keep the air intake in a normal state;

4. There is no sludge blockage after cleaning. If the throttle valve still maintains its previous opening, the intake air volume will be too large. As a result, the engine will shake when starting, and the acceleration will be weak, and the engine fault light may light up. Then why does the engine sometimes work normally without initialization after cleaning the throttle? That's because the throttle is not too dirty, and its intake has not changed much after cleaning.
