What will happen to Yang Guangjiao's couple after adjusting the idling screw?

Can't be adjusted to the lowest according to the manufacturer. His idle screw is to adjust the throttle for easy cleaning. Can't you see that you can only go up and not down? Just wash it and transfer it back. I'm not saying that all EFI cars that adjust the idle speed for you have idle motors. Start it when it is adjusted, which will not help the hot car. Because the computer recognizes that you are automatically injecting fuel at the fuel filler door, it will stop even if it is slightly raised, which will not help the hot car start, that is, it will be more difficult to start the hot car in slow and cold weather.
