The cause of the Trumpchi GS4's vibration during startup is that the vehicle shakes when the clutch pedal is slowly released from a stationary position to begin moving. The reasons and solutions for car idle vibration are as follows: 1. The driven plate steel sheet is broken, or the rotating parts' dynamic balance does not meet requirements, causing the clutch to shake. Solution: Replace the parts or re-weld the driven plate hub. 2. Loose engine mounting or misalignment between the transmission's first shaft and the engine crankshaft's centerline can easily cause the clutch to shake. Solution: Tighten the engine or replace the parts. 3. Poor contact of the clutch lining, surface hardening, or adhesion of glue-like substances can easily cause the clutch to shake. Solution: Re-weld the clutch lining. 4. When the driven plate is warped, skewed, or deformed, the clutch lining will have irregular contact during the clutch engagement process. Solution: Correct or replace the driven plate.

I've been driving the Trumpchi GS4 for several years, and the idle vibration is quite annoying. There are several common causes: First, engine carbon buildup issues, where unstable idle speed occurs due to carbon deposits in the cylinders affecting combustion efficiency. Second, ignition system failures, such as worn spark plugs or damaged ignition coils, leading to misfires in a cylinder. Third, fuel system problems, like clogged injectors or insufficient fuel supply, causing the engine to shake. Fourth, a dirty mass airflow sensor sending incorrect data to the control computer. Fifth, aging engine mounts reducing their damping ability. I believe this affects fuel consumption, and long-term neglect can damage parts. It's best to regularly clean the throttle body and check the spark plugs. If the vibration is severe, promptly visit a repair shop for professional diagnosis. Preventive measures are simple: use higher-grade gasoline more often and drive on highways to clear carbon deposits.
