Can the electronic throttle be changed into a cable throttle? . . . Is it complicated? . As the title. . .

In modern cars, the throttle is controlled by a computer. According to the position of the electronic throttle, the computer comprehensively considers the factors such as vehicle speed and air-fuel ratio, and controls the opening of the throttle and the amount of fuel injected into the cylinder by calculating and issuing control instructions for the throttle and the gasoline EFI.

If the throttle is changed to wire control, the computer can't control the fuel injection according to the actual situation, and the engine can't work unless the whole fuel supply system is changed to carburetor.
