A damaged purge control valve can significantly affect engine performance in your Suzuki Cultus, as it plays a critical role in the evaporative emission control EVAP system. When the valve fails, it can lead to:

Engine Hesitation: The engine may hesitate o r experience delays when accelerating because the fuel vapor flow is disrupted. This can feel like a lag in power when you step on the gas.

Rough Idling o r Stalling: If the valve stays open o r closed when it shouldnt, it can lead to an imbalance of air and fuel in the engine, causing irregular idling. In more severe cases, the engine may stall when stopping at traffic lights o r during low-speed driving.

Reduced Power and Acceleration: The engine may not receive the correct amount of air/fuel mixture due to improper vapor handling, which can impact acceleration and overall engine power.

Increased Emissions: A faulty valve can allow fuel vapors to escape, leading to higher emissions and potential environmental issues.
