What do you mean by the wrong throttle? Will it directly lead to an air crash?

When the plane takes off, the thrust is the maximum takeoff thrust, that is, the maximum thrust that the plane can use. Let's talk about that plane in transasia airways. When it took off, it flew almost at full speed. However, after launch, the engine on the left side of the plane failed, and the left side of the plane lost thrust and lift, so the plane would lean to the left and the left side lost altitude. However, if the pilot carries out the emergency procedure of single engine failure to pull up the plane at this time, there is no problem at all. But the pilot stepped on the wrong accelerator and turned off the right engine, causing the plane to lose all thrust, and then the plane fell like a glider. The accident report was that the No.2 engine of the aircraft broke down, and then the pilot turned off the No.2 engine 1, and the No.2 engine automatically changed from the system to the downstream state, which means that all the engines did not work. (No.1 is left hair, No.2 is right hair)

Since the pilot turned off the engine of 1, the subsequent single engine failure procedure may be carried out by the pilot according to the engine failure of 1.
