What are the common engine problems in a Ford S-Max?

I have noticed some issues with my Ford S-Max's engine and I am wondering what could be causing it. It seems to have less power and sometimes makes strange noises. Can someone provide some insight on what could be causing these problems?

It could be due to a number of reasons, including a faulty catalytic converter or a failing fuel injector. I would recommend taking your car to a mechanic for a thorough inspection to pinpoint the exact issue.

I had a similar problem with my Ford S-Max and it turned out to be a faulty oxygen sensor. I suggest getting this checked and replaced if necessary as it can greatly impact the engine performance.

It could also be a problem with the spark plugs or ignition coils. These are relatively easy and inexpensive to replace, so it's worth checking these components as well.
