Why is my Ford Galaxy's engine stalling while idling?

I recently bought a Ford Galaxy and have noticed that the engine tends to stall when idling for a long time, like at a red light. It never happens when driving, only when the car is idling. What could be causing this and how can I fix it?

This could be caused by a number of things such as a faulty idle air control valve, dirty fuel injectors, or even a clogged air filter. It's best to take your car to a trusted mechanic for a thorough diagnostic check to determine the exact cause of the problem.

I had the same issue with my old Ford Galaxy. It turned out to be a bad oxygen sensor. I suggest getting it checked and replaced if necessary.

My dad is a mechanic and he says that this is a common problem with Ford Galaxys. It's usually caused by a dirty throttle body. You can try cleaning it yourself with some throttle body cleaner or take it to a mechanic for a professional cleaning.
