04 model 323 1.8 fuel consumption 13 liter. What happened? Please answer the master! thank you

This fuel consumption is really high. Actually, it's almost nine. It's a fault.

The vibration sound is the opening and closing sound of the solenoid valve core of the activated carbon tank, which belongs to the normal operation of the valve when it is hot started. This is normal, and the system controls the cleaning of the carbon canister;

When waiting for a red light, it is not recommended to set the gear in D, but in P or neutral, which is beneficial to the normal use of the transmission and the oil temperature is too high.

D jitter, clean the throttle, clean the fuel system;

The problem of high fuel consumption-besides driving habits, it is also necessary to test the performance of the intake pressure sensor. The sensor signal is no longer in the standard range, which will lead to the imbalance of mixing ratio. At the same time, don't ignore whether the fuel pressure is too high.
