Remote control car direction is full of body vibration.

The reason why the remote control vehicle vibrates in the direction of the vehicle body is that the engine has serious carbon deposition. According to relevant public information, if the throttle valve is too dirty or the fuel injector has too much carbon deposit, the remote control car will vibrate when refueling the car body in the direction. When there is too much carbon deposit in the engine, the gasoline sprayed by the injector will be absorbed by a large amount of carbon deposit during cold start, which leads to the lean mixture during cold start and the difficulty in starting.
