1. If it is rainy/there is water on the road, and oil can't be added at this time, it is recommended to turn off the engine and open the front cover of the vehicle to check whether there is water vapor that leads to engine ignition failure. If there is water, it is recommended to wipe the water vapor clean in time, which can basically eliminate the fault;

2. Check the engine air filter. If the engine air filter is blocked/damaged, the engine air intake is not smooth, resulting in poor combustion of the vehicle and slow engine operation. Therefore, when the air filter is blocked, it should be cleaned in time, and when it is damaged, it should be replaced with a new air filter in time to keep the air inlet of the engine open and ensure the air entering the body as clean as possible.
