1. The engine is difficult to start and very easy to stop.
It often needs a second ignition, and it is very easy to extinguish again after the ignition.
2. The car makes a strange noise when driving.
The specific performance is that under non idle state, sometimes a "da da" sound can be heard.
3. The fuel consumption increases, and the smell of gasoline in the car is large.
4. The idle speed of the engine varies from high to low, and the acceleration is weak.
After the engine is started, the idle speed fluctuates regularly from high to low, and the vehicle is unable to accelerate.

After the carbon canister has stored gasoline vapor, when the engine starts again, the solenoid valve installed between the active carbon canister and the intake manifold opens, and the gasoline vapor in the active carbon canister is brought into the cylinder by clean air under the vacuum of the intake manifold for combustion.
So it is important to know that the carbon canister and the carbon canister solenoid valve only belong to the same system - the gasoline evaporation control system (EVAP), but the carbon canister and the carbon canister solenoid valve are not the same thing.
A simple understanding is that carbon canister is used to absorb gasoline vapor, equivalent to a container.
The carbon canister solenoid valve is a valve that controls the gasoline vapor in the carbon canister to enter the engine for combustion.
It is equivalent to a switch.
