The car of Geely Freedom Ship started running at 120, and the throttle vibration was great.

According to your description, whether the engine vibrates or not, provide the following detection scheme:

First: Check whether the primer of the engine and gearbox is worn, aged and loose.

Second, check whether the gap between the ignition heads of the spark plugs is too large and whether there is too much carbon deposit, which leads to poor electric jump and affects the combustion quality of the engine. It is recommended to replace.

Third, check whether the ignition coil works normally and replace it in time if there is any problem.

Fourth, check whether the gasoline pressure is insufficient. Are the fuel injection quantities of the four nozzles consistent? It is recommended to clean the nozzle.

I hope my answer can help you! If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
