How do I troubleshoot a rough idle on my Ford Galaxy?

I have a Ford Galaxy that has been experiencing a rough idle lately. It feels like the car is shaking and the RPMs are fluctuating between 500-1000. I'm not sure what could be causing this issue. Any advice on how to troubleshoot and resolve this problem would be greatly appreciated!

Based on your description, it sounds like there may be an issue with your fuel system. I recommend checking for any clogged fuel filters or dirty injectors. It's also a good idea to run a diagnostic test to see if any error codes pop up.

I had the same issue with my Ford Galaxy a few months ago and it turned out to be a faulty spark plug. I would recommend checking and potentially replacing all of your spark plugs to see if that improves the rough idle.

Another possible cause for a rough idle could be a vacuum leak. Check all of the hoses and connections in your vacuum system to make sure they are secure and not damaged. A simple fix like replacing a hose could solve the issue.
