What Causes Shaking While Driving a New Car?

[McCali]

New car shaking during driving can be caused by the following reasons: Intake system malfunction: Minor air leaks or small blockages may appear normal at idle, but during rapid acceleration, severe shaking, lack of power, and illuminated engine warning lights may occur. Ignition system failure: Ignition high-voltage wires rarely fail, but ignition coils and spark plugs are wear-prone components. Worn spark plugs or using inferior quality spark plugs can cause power loss and acceleration shaking. Fuel system issues: During acceleration, especially in manual transmission vehicles, depressing the clutch for gear shifting may cause the RPM to drop significantly with accompanying shaking (similar to engine stalling due to insufficient power).
