According to the situation you described, we analyze that the main cause of the failure may be insufficient engine power. Generally speaking, the main reason for this kind of fault is that there are more carbon deposits in throttle, air inlet and injector. After cleaning up the internal carbon deposit, the fault should be eliminated. Because of the limitation of the fault phenomenon you described, in order to analyze the specific causes of the fault, we still have to go through the real vehicle diagnosis to find the specific fault point.
