How can Karvaan owners detect early signs of a faulty purge control valve?

Common symptoms include rough idle, difficulty starting, increased fuel consumption, o r a fuel smell near the engine bay. Are Karvaan users in Pakistan able to identify these symptoms in time?

Early symptoms include:

Rough engine idle

Difficulty starting, especially after refueling

Decreased fuel efficiency

Fuel odor near the engine bay o r inside the cabin

Check Engine Light CEL turned on

Unfortunately, many drivers ignore these early signs until performance worsens o r the engine check light persists.
