If you think the vehicle costs oil, please ask a professional technician to help you check whether the data flow of each sensor is within the normal range when the engine is working normally. Focus on the data of oxygen sensor, water temperature sensor, throttle position sensor, intake pressure or air flowmeter, and judge the general fault direction through the display of data.

Check the throttle, intake pipe, valves and fuel injectors for carbon deposition and clean them up. Check whether the ignition system works normally and whether there is leakage caused by aging of the ignition coil or cylinder pipeline. Check whether the gasoline pressure is normal and whether the fuel injector leaks.
