What are the reasons for severe car shaking sometimes?
2 Answers
The reasons for severe car shaking sometimes are: 1. Severe engine carbon deposits; 2. Faulty spark plugs or ignition coils; 3. Unstable car oil pressure; 4. Aging engine components; 5. Poor fuel quality; 6. Transmission failure, unable to function properly. The solutions for severe car shaking sometimes are: 1. Read fault codes or data streams to eliminate sensor faults; 2. Check if the exhaust valve has any issues; 3. Inspect spark plugs, high-voltage wires, ignition coils, fuel injectors, timing marks, fuel pump pressure, and cylinder pressure; 4. Check if the idle control motor has any problems, clean the throttle body and idle control motor.
I've been driving for several years and sometimes experience severe car shaking, especially when waiting at traffic lights. Once, I thought it was an earthquake, but it turned out to be due to aging spark plugs or faulty ignition coils, causing engine misfire and uneven power output leading to shaking. Additionally, issues in the fuel system, such as clogged fuel injectors or a dirty fuel filter, can cause uneven combustion and make the car shake. If ignored for a long time, it may lead to more engine carbon buildup and damage the catalytic converter. So, I recommend checking the spark plugs and fuel system every 10,000 to 20,000 kilometers and regularly cleaning the throttle body to prevent further issues and ensure a smoother ride.
