What Causes Car Shaking After Starting?
1 Answers
Reasons for car shaking after starting: 1. Excessive carbon deposits, caused by too much carbon buildup on the engine, throttle valve, or fuel injectors leading to engine shaking; 2. Spark plug gap too large or too small, excessive carbon deposits on spark plugs, damaged ignition coils, or loose/leaking high-voltage wires; 3. Unstable oil pressure which easily causes unstable mixture concentration resulting in car shaking and unstable idling; 4. Dynamic balance issues - when replacing new tires, if dynamic balancing isn't performed, steering wheel shaking may occur during high-speed driving, and tire bulges or deformations can also have an impact; 5. Steering gear problems - since the steering gear tie rod ball joint is movable, excessive wear can make steering inaccurate and cause tire shaking; 6. Aging rubber bushings on the fixed steering gear can also cause shaking when turning the steering wheel.
