What Causes Continuous Leg Shaking When Pressing the Accelerator?
2 Answers
Here are the reasons for car shaking when pressing the accelerator: Fuel system issues: Fuel system problems are usually caused by fuel line blockages, leading to poor fuel supply, manifested as engine shaking, unstable idling, or stalling while driving. Additionally, fuel pump failure can also cause engine shaking. To diagnose fuel pump issues, disconnect the fuel line and check the flow rate and volume. Ignition system malfunction: For the engine to operate properly, it requires sufficient air, adequate gasoline, and a well-functioning ignition system. Any issues in these areas can cause the engine to shake. If there is a leak or blockage in the intake system, the car may experience acceleration shaking when pressing the accelerator.
As someone who has been repairing cars for many years, I've encountered numerous drivers complaining about leg trembling when pressing the accelerator. Typically, this stems from vehicle-related issues, such as vibrations from the throttle pedal transmitting to the leg, possibly due to engine imbalance or worn suspension components. During long-distance driving, older vehicles are particularly prone to this, especially in urban traffic with frequent stops and starts. Large fluctuations in engine RPM or a worn clutch can also intensify pedal vibrations. It's advisable to regularly maintain and inspect the engine and suspension, tighten loose components, and replace aged parts. Unbalanced tires are another common trigger—maintaining proper tire pressure can reduce unnecessary vibrations. Safety comes first; neglecting these hidden issues may compromise vehicle performance over time or lead to more severe malfunctions. Prompt inspection at a professional shop can always prevent unexpected problems.
