What to Do When the Car Has Strong Jerking Sensation?
2 Answers
Solutions for strong car jerking sensation: 1. Pay attention to cleaning carbon deposits from the throttle, fuel injectors, and intake ducts; 2. Use qualified fuel for more complete combustion; 3. Have it checked and repaired at a maintenance shop to avoid more potential safety hazards. Causes of strong car jerking sensation: 1. For manual transmission models, accelerating or decelerating while driving in a semi-clutch state can cause jerking, with deeper throttle input leading to more pronounced jerking; 2. For automatic transmission models, there may be slight jerking when accelerating and upshifting, with more noticeable sensations when forcefully downshifting and then upshifting with heavy throttle; 3. Excessive carbon deposits in the throttle, fuel injectors, and intake ducts; 4. Use of unqualified fuel leading to incomplete combustion; 5. Faults in spark plugs, ignition coils, etc., causing cylinder misfires.
I've been driving for over 20 years and have encountered stuttering issues several times, usually related to engine components. For example, when spark plugs age or ignition coils fail, the car will jerk during acceleration. Poor fuel quality is also a factor—last time I used low-grade gasoline, the stuttering was severe, but it improved significantly after switching to high-quality fuel. Carbon buildup in the throttle body or fuel injectors can also cause incomplete combustion, leading to shaking. For manual transmissions, abrupt clutch engagement or inaccurate gear shifts can easily cause jerking; for automatic transmissions, dirty fluid or control module failures may lead to stuttering. I recommend starting with simple checks, such as spark plugs and air filters, and if that doesn’t help, take it to a repair shop for professional diagnosis. Remember, don’t ignore it for too long, or engine wear will worsen. Developing a smooth driving habit can avoid additional wear and tear.
