The reason why the throttle is too heavy.

The reasons and treatment methods related to the increase of throttle weight are as follows. First, this phenomenon is caused by the dirty accelerator of the vehicle. It is recommended to clean the throttle and then re-match the throttle. If it is the throttle of the cable, in this case, the aging of the cable will also cause the throttle to become heavier, and a new cable needs to be replaced. Secondly, the pedal shaft related to the position of the vehicle accelerator pedal is too tight or too dirty, which leads to the heavy accelerator. In this case, it is recommended to lubricate the pedal shaft. Third, the lack of engine power will also lead to this situation. In this case, it is necessary to clean up the carbon deposit inside the engine and check the state of the spark plug. If the spark plug is aging and the ignition gap is too large, the throttle will become heavy, so it is necessary to replace the spark plug in time. Fourthly, it is necessary to check the brake vacuum booster and the brake vacuum booster motor, which is caused by the problem of the vehicle brake vacuum booster system. To sum up, if the accelerator becomes heavier, it needs to be repaired in time, otherwise it will affect the normal driving operation of the vehicle.
