Correcting throttle

1. When the accelerator pedal is depressed, the throttle opening increases and the air intake increases. Engine ECU corrects and increases the fuel injection quantity according to the intake air quantity, throttle position sensor signal and signal change rate. If you step on the accelerator, the intake air volume will increase less, and the corrected fuel injection volume will also increase less, or the fuel injection volume of the injector will increase slowly or less, so the acceleration will be slow;

2. If you step on the accelerator, the air intake will increase sharply, but if the sensor signal is wrong, the fuel injection quantity of the injector will not increase or increase very little, or the ignition high pressure is weak, the engine speed will decrease.
