Why does my Ford Focus have a rough idle?

I recently noticed that my Ford Focus starts to shake and vibrate when idling. Is this a common problem with this model? What could be causing this issue and how can I fix it?

Hi Maria, a rough idle can be caused by several factors such as dirty fuel injectors, faulty spark plugs, or a clogged air filter. I would suggest checking these components first and cleaning or replacing them if necessary. If the issue persists, it may be a problem with the engine itself and it should be checked by a mechanic.

Hi Maria, I had the same issue with my Ford Focus and it turned out to be a faulty ignition coil. I had it replaced and the rough idle went away. I would recommend getting it checked by a mechanic to confirm the issue and replace any faulty components.

Hi Maria, I had a similar experience and it was due to a vacuum leak in the engine. This can cause the engine to run rough and produce excessive vibrations. I would suggest getting the vacuum lines checked and replaced if necessary.
