What Causes Vehicle Body Shaking During Acceleration?

[MacLorenzo]

Reasons for vehicle body shaking during acceleration: 1. Carbon buildup in the engine; 2. Carbon deposits on spark plugs; 3. Abnormal fuel pump pressure; 4. Aging engine components; 5. Deformation of clutch pressure plate and friction disc; 6. Dirty throttle body; 7. Incorrect ignition timing. Correct steps for starting a car: 1. Insert the key into the ignition switch and turn it one notch upward for system self-check; 2. Depress the clutch and start the vehicle (dashboard lights will illuminate); 3. Press the clutch and engage first gear; 4. Release the handbrake, wait until the car shows tendency to move forward, then gradually release the clutch while applying throttle to start.
