Why is my Ford Mondeo sputtering while idling?

I recently noticed that my Ford Mondeo is sputtering when I come to a stop. It seems to happen more often when the car is idling for a longer period of time. What could be causing this and how can I fix it?

This could be due to a dirty fuel filter or spark plugs. I recommend getting them checked and replaced if necessary.

Another possible cause could be a faulty idle air control valve. I suggest having a mechanic take a look at it.

Make sure your air filter is clean and properly installed. A clogged air filter can also cause sputtering.
