Ea888 throttle is too thin.

Ea888 throttle is too thin. The possible reasons are as follows:

Air leakage in the first air intake system will lead to the mixture being too lean. It is recommended to check whether the dipstick is tightly inserted, whether the oil cover gasket is aging and whether the waste gas valve is damaged.

The second air-fuel ratio is wrong, so it is suggested to check whether the throttle valve is dirty, which will also lead to too lean mixture.

Check whether the atomization of the fuel nozzle is good. If EA888 engine is equipped, it is recommended to clean the fuel nozzle. It is difficult to observe the nozzle of a direct injection engine because it is difficult to disassemble it. It is recommended to check the engine computer for fault codes related to oxygen sensors. If you are not advised to read the data stream again to confirm the troubleshooting of the oxygen sensor, these will lead to the lean mixture of the engine.
