Regarding the starting vibration you asked about, this fault should be that three groups of clutches (flywheel, clutch plate and pressure plate) are irregularly worn, causing one or more of them to swing. During the engagement process, the clutch plates can't engage smoothly, but engage at one point and release at another point, which makes the engine power just start to transfer and suddenly slip, and the vehicle behaves like a trip. In this case, it is necessary to check not only the three-plate clutch, but also whether the center point of the first shaft of the gearbox and the flywheel are on the same straight line and parallel. If there is a problem in this respect, even if the clutch three-piece set is completely replaced for a period of time, the vehicle will start to shake. There is also the aging or fracture of the rubber of the engine claw, which will also lead to this phenomenon. You need to investigate the reasons for the above analysis one by one.
In addition, your car has run more than 1 10000 kilometers, so I suggest you do maintenance every 5000 kilometers.
