What happened to the engine jitter and unstable idle speed during the rapid acceleration of Buick Lang Wei 1.5T model?

This car is very new, there will be no serious carbon deposit failure, and the accessories will be fine. We should consider the problem of oil circuit. Maybe the fuel that occasionally appears in magazines recently will exceed the standard, and so will the fuel of China Petrochemical Company. Why else would people clean the underground oil tank in February? Now clean the oil circuit directly, and the problem will be solved. I just fill the fuel filter tank directly, and there will be no idle jitter.
