Why does the car shake when stepping on the accelerator at high speed?
1 Answers
High-speed acceleration causes car shaking due to: 1. Dirty throttle body; 2. Carbon buildup in fuel injectors, spark plugs, throttle body, or cylinders; 3. Malfunctions in engine, half shafts, fuel system, or ignition system; 4. Insufficient cylinder pressure; 5. Aging engine components. Solutions for high-speed acceleration shaking: 1. Replace filters (engine oil filter, fuel filter, air filter) to improve filtration and reduce impurities for better combustion; 2. Clean carbon deposits from fuel injectors, spark plugs, throttle body, and cylinders; 3. Replace worn engine components.
