Stalling Is Usually a Symptom, Not a Cause

When a car stalls at idle, it's telling you the engine can't sustain itself without throttle input. But that can happen for several different reasons โ€” and the most likely one depends entirely on your vehicle's make, model, fuel type and mileage.

Stalling at a busy junction or roundabout is a genuine safety risk. Power steering and power brakes both rely on the engine running. Don't put off diagnosing this.
