Why is my Ford Galaxy engine Revving at Idle?

Recently, my Ford Galaxy's engine has been revving at idle and I'm not sure what's causing it. It seems to happen randomly and it's becoming a concern. What could be causing this and how can I fix it?

This could be a sign of a vacuum leak or a faulty idle air control valve. I recommend taking your car to a certified Ford mechanic to have it checked out as soon as possible.

I had a similar issue with my Ford Galaxy and it turned out to be a faulty oxygen sensor. I suggest getting that checked out.

It could also be a problem with your spark plugs or ignition system. Have those checked out as well.
