Peugeot 207 1.4 is manual, and the engine makes abnormal noise when refueling.

Cleaning the throttle and AB maintenance is the normal maintenance of 25,000 kilometers.

There's nothing wrong,

But there is something wrong with the original sound after washing the throttle.

This maintenance related to the engine is to remove the throttle, wash the throttle and change the oil. Regardless of other reasons, it is estimated that there is no gas cabin to protect the gas cabin, so there is a sound when refueling urgently, and it is a bit boring to drive and refuel;

Go to the original maintenance place for inspection.
