When a swirl control valve is malfunctioning, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions. Symptoms may include rough idling, hesitation during acceleration, or the engine warning light illuminating. A faulty valve can cause improper air-fuel mixture, affecting combustion and overall engine operation. In some cases, it may result in a loss of power or unexpected engine stalling.
