2. There is a problem with the carbon canister or the solenoid valve of the carbon canister, which leads to the mixture being too rich;

At this time, the driving computer will appropriately increase the fuel injection quantity according to the intake temperature and water temperature signals, and the fuel injection quantity will increase. In addition, a very small amount of oil and gas will be discharged, so it will smell a heavy gasoline smell. When the car reaches normal temperature, the oil and gas in the cylinder can be fully burned, and naturally there is no smell of gasoline.
