What are the most common engine problems on the Ford Transit Custom?

I have recently noticed that my Ford Transit Custom is making some strange noises and the performance seems to be lacking. I am worried that it may be a serious engine problem and I'm not sure where to start troubleshooting.

It's possible that there could be an issue with your spark plugs or ignition coils. These are common culprits for strange engine noises and decreased performance. I would recommend getting those checked and replaced if needed.

Another possibility could be a clogged fuel filter. This can cause poor engine performance and even lead to engine damage if left untreated. Make sure to get it checked and replaced regularly.

Try checking your air filter as well. A dirty or clogged air filter can also lead to engine problems and impact your car's performance. Consider replacing it if it looks dirty.
