What are the reasons for severe car shaking sometimes?
4 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.
I remember the last long-distance road trip when the car suddenly started shaking violently on the highway, scaring me into pulling over immediately. At the repair shop, they found that the front wheel rim was slightly deformed, and the balancing weights had fallen off, causing wheel imbalance. The technician said uneven tire pressure or worn bushings in the suspension system could also cause this, especially at higher speeds. Additionally, if the brake discs are unevenly worn, the car would shake badly when braking. Since then, I've been checking tire wear and doing wheel balancing every few months to ensure safe driving.
When encountering severe car shaking, I immediately pulled over and turned off the engine to inspect. This could be due to damaged suspension shock absorbers or loose control arms, which are especially dangerous on bumpy roads and may lead to loss of control. Faulty spark plugs or unstable oil pressure can also cause engine shaking, and sometimes the throttle valve needs cleaning if it's too dirty. For driving safety, don't push through—find a reliable repair shop to address the issue as soon as possible.
