What Causes the Car to Jerk, Feel Weak, and Fail to Accelerate When Pressing the Accelerator?
1 Answers
The reasons why the car jerks, feels weak, and fails to accelerate when pressing the accelerator are as follows: Clutch slippage: Mainly manifested as the car's speed not increasing with the engine's RPM during acceleration, where the engine's power is not fully transmitted to the drive wheels, resulting in weak driving performance, especially noticeable when going uphill. Engine issues: The power source comes from fuel combustion, and the engine is responsible for supplying fuel and converting chemical energy into mechanical energy. Therefore, when the car struggles to accelerate or feels sluggish, the engine system should be a key focus for inspection. Engine oil system: The importance of engine oil is self-evident—it ensures sufficient lubrication, reduces resonance, and enhances the smoothness of engine operation. If the engine oil is insufficient for a long time, it can lead to insufficient power and increased fuel consumption in mild cases, or piston impact on the valves causing mechanical damage to related components in severe cases. Additionally, a faulty fuel pump or a clogged fuel filter can also result in reduced engine power.
