What are the symptoms of a faulty Wuling Rongguang carbon canister?

[JeffreyAnn]

The symptoms of a faulty Wuling Rongguang carbon canister are as follows: 1. Gasoline smell inside the car or around the vehicle (carbon canister damage): If the carbon canister is damaged, the adsorbed fuel vapors inside will directly escape into the air, causing a strong gasoline smell inside the car or around the vehicle. 2. Erratic idle speed (carbon canister clogging): If the air inlet or filter of the carbon canister is clogged, the adsorbed fuel vapors inside will have difficulty being drawn into the cylinders by the intake manifold vacuum, leading to fluctuating idle speeds. 3. Difficulty starting the engine (carbon canister purge valve stuck open): Since the carbon canister purge valve remains open continuously, the intake air will be saturated with fuel vapors. When starting the engine, the overly rich air-fuel mixture can cause difficulty starting or even stalling.
