Why does the car sometimes fail to accelerate when driving?

[MasonDella]

The reasons why the car sometimes fails to accelerate when driving are: 1. The fuel level in the fuel tank is too low to achieve normal adsorption pressure; 2. Blockage in the fuel line, causing low fuel pressure and weak acceleration; 3. Malfunction of the throttle pedal sensor; 4. Fault in the throttle body. Precautions for pressing the accelerator pedal are: 1. Press and release the accelerator pedal gently and smoothly; 2. Coordinate the release of the clutch with pressing the accelerator pedal promptly and accurately; 3. Choose an appropriate gear to keep the engine running at medium speed and larger throttle opening most of the time to save fuel; 4. Before stopping or turning off the engine, release the accelerator pedal first and avoid revving the engine abruptly.
