Skoda Praktik Engine Stalling At Idle

That sounds like a faulty idle air control valve. The check engine light and stalling are definite red flags. When the engine is idling, the idle air control valve regulates the amount of air entering the engine, ensuring a smooth and consistent idle. A contaminated intake can mess with this delicate balance. Have you noticed any other symptoms, like a rough engine idle or hesitation when accelerating?

Rough engine idle describes it well, and hesitation too. What exactly do you mean by contaminated intake, and what is its relationship to the idle speed?

Contaminated intake refers to a buildup of dirt, oil, and carbon deposits inside the intake manifold. This restricts airflow, and the idle air control valve struggles to compensate, leading to unstable engine idle and stalling. Given the symptoms, it's very likely the issue. A professional cleaning, or even replacement, of the valve and intake is probably needed. I'd recommend taking it to a workshop for diagnosis and repair as it can affect the car idle dramatically.

The workshop visit confirmed a contaminated intake. A new idle air control valve and a cleaning cost 425€. The engine idle is stable, and the stalling is resolved. Thanks for the assistance.
