Why is the car accelerating slowly?

[JamesLee]

The slow acceleration of a car is related to the valves in the engine or the valve timing, among other factors. Check if the tire pressure meets the standard: Low tire pressure increases the friction between the tires and the ground, which in turn increases resistance. Higher resistance leads to increased fuel consumption, ultimately resulting in insufficient air intake and causing the car to accelerate slowly and lack power. The root cause of slow acceleration is increased fuel consumption: Excessive carbon deposits, prolonged use of the oxygen sensor, and contamination of the intake system can all lead to increased fuel consumption. When these issues occur, they directly affect the engine's cylinder compression ratio, causing insufficient combustion force when the gasoline burns.
