What's the matter with the gas car not being able to add the throttle?

This situation may be caused by the damage of air flow meter, or insufficient cylinder pressure and damage of ignition coil. Check whether there is a problem with the gas pressure valve, otherwise the pressure may not be reached. The throttle position sensor is too dirty or the voltage is unbalanced, which will also cause the throttle to fail to engage. Try to judge whether there is something wrong with the accelerator pedal of the car, because when stepping on the accelerator, the cable will drive the accelerator, that is, the accelerator, which has a position sensor. The control unit knows the throttle opening according to the signal of the throttle position sensor, then calculates the corresponding signal voltage, and finally calculates the fuel injection quantity of the vehicle according to the signal voltage. The oil system of the engine is also very important. If inferior gasoline is added, it is likely to cause gasoline pump combustion, three-way catalytic failure, piston failure and so on. , will directly affect the engine power, easy to cause engine flameout, speed can not be improved. When the performance of the spark plug is degraded or the inferior spark plug is used, it will also cause the car to be unable to accelerate and accelerate.
