What Causes Vibration After Vehicle Startup?
1 Answers
The reasons for vibration after vehicle startup are: 1. Abnormal fuel pump supply pressure or incorrect readings/malfunction of the intake pressure sensor; 2. Aging of engine components or engine mounts; 3. Dirty throttle body or excessive carbon buildup in fuel injectors; 4. Abnormal engine coolant temperature. The vehicle starting procedure is: 1. After sitting in the driver's seat, press the start button once for ACC light, then press again for system self-check; 2. Depress brake pedal and press engine start button for ignition; 3. Release foot brake and optionally warm up the engine; 4. Depress brake pedal again, shift to D gear and release parking brake (for electronic parking brake, simply press the button); 5. Gradually release foot brake to complete the starting process.
