What is the reason for the heavy throttle?

1. If the engine oil is added too much, the internal resistance will increase when the engine is running, resulting in a slow increase in engine speed after stepping on the accelerator. Pay attention to the fuel gauge when refueling, and add it to the scale of the fuel gauge normally.

2. If the viscosity of the oil is too high, the internal resistance of the engine will be too high when it is running, so that the engine speed cannot rise quickly after stepping on the accelerator.

3. The problem of spark plug and ignition coil will also lead to the phenomenon that the engine can't accelerate slowly after stepping on the accelerator. Spark plugs should be replaced regularly. If it is not replaced for a long time, the gap between spark plug electrodes will increase, which will also lead to excessive carbon deposition on spark plug electrodes. When selecting the engine oil model, it should be selected according to the technical characteristics of the engine.

4. In the process of acceleration, if you feel that the throttle of the car is heavy, it may be because the spring under the throttle is too hard, or it may be because the spring is too elastic. The throttle spring should be corrected or replaced in the repair shop according to the specific situation. Million car purchase subsidy
