Why does the car feel like it's cutting off fuel when stepping on the accelerator?

Every system in a car consists of numerous components, and if any one of them malfunctions or experiences abnormalities, it can cause the car's engine to shake during acceleration. Here is some extended information about common car faults: 1. Intake System: The intake system is another common source of faults. If the throttle opening does not increase when the accelerator is pressed, the engine requires more combustible air-fuel mixture to support higher RPMs. However, if the air intake decreases, it can result in a feeling of powerlessness. 2. Fuel System: If low-quality gasoline is used, it may lead to issues such as fuel pump burnout, catalytic converter failure, or piston problems, directly affecting engine performance. This can easily cause the engine to stall or fail to accelerate properly.
Last time I encountered a similar issue, it felt like the car suddenly lost power when I stepped on the accelerator, shaking violently. My friend mentioned this could be a problem with the fuel system, such as an aging fuel pump causing insufficient fuel supply, or a clogged air filter leading to poor air intake and affecting the air-fuel mixture ratio. It might also be due to excessive carbon buildup in the fuel injectors blocking the fuel lines. During routine checks, remember to inspect these areas for cleanliness or whether the fuel quality in the tank has deteriorated from using substandard gasoline. It's advisable to promptly visit a professional repair shop for diagnostics—don’t delay, as sudden fuel loss during high-speed driving can be very dangerous. You might try switching gas stations or adding a bottle of fuel additive to clean the fuel system. Regularly replacing the fuel filter and maintaining the engine on schedule can also help prevent these issues.
