What is the purpose of the EVAP system and Vapor Canister on Mercury Grand Marquis?

The EVAP system in 2002 and later models traps and stores fuel vapors from the fuel tank and intake manifold. It includes a charcoal canister and various lines. When the engine is off, vapors are stored in the canister, and when on, they're purged by a solenoid and used in combustion. Issues like poor idle, stalling, or fuel odor could indicate problems with the purge control solenoid, canister, or hoses. Visual checks for leaks and electrical connections are recommended, with further diagnosis and potential component replacement by a professional repair facility.
