What are the symptoms of a bad charcoal canister?

[Willis]

Here are the symptoms of a faulty charcoal canister: 1. Decreased fuel economy: Leakage in the charcoal canister or its pipes, or a malfunctioning solenoid valve, can cause fuel vapor to escape into the atmosphere. This inevitably leads to fuel wastage, with the direct manifestation being increased fuel consumption. 2. Reduced engine power and jerky acceleration: Leakage in the charcoal canister pipes or a solenoid valve stuck in the open position can allow a large amount of air to enter the engine intake along with fuel vapor, resulting in an overly lean air-fuel mixture. This can cause poor engine combustion, leading to reduced power and jerky acceleration. This phenomenon becomes more noticeable when the vehicle is fully loaded. 3. Strong gasoline odor inside the car: If you notice a strong gasoline smell inside the car while driving, the charcoal canister should be considered a primary suspect. Whether it's a cracked charcoal canister shell or leaking pipes, both can cause a large amount of fuel vapor to be released directly into the atmosphere. These fuel vapors can enter the car through gaps or be drawn into the cabin by the blower when the air conditioning is turned on, resulting in a strong gasoline odor inside the car.
