My Tianyu sx4 1.6 automatic transmission, what is the body shake?

Hehe, if you put your hand on the steering wheel when you are in N gear, if you can feel the shaking badly, nine times out of ten it is carbon deposit. If you are in the D gear and step on the brakes, you say that most of the situation should be normal, because at this time your engine is working and you are stepping on the brakes to stop the car from moving forward, and that force is always balanced and cannot disappear for no reason. See if you have more traction or braking force. When you step on the brake at idle speed, there is no doubt that the braking force is greater than the traction force, so the work done by the engine will be transferred to your bearing through the crank, and then the bearing will continue to transfer the force to the brake pad. Because your steering column and bearing are connected together, you will feel that the steering wheel is shaking obviously and the carbon deposition is not very severe. Don't take the method of disassembling the cylinder to clean the throttle, because once the cylinder is disassembled and cleaned, the effect is obvious, and then your engine noise will increase sharply.
