What are the most common issues with the Ford S-Max engine?

I recently purchased a used Ford S-Max and I've been having some issues with the engine. It seems to be struggling when starting and the performance is not as smooth as I expected. I'm concerned about what might be causing these issues and how I can prevent them in the future.

Based on my experience with Ford cars, I would advise you to check the spark plugs and ignition coils. These are often the cause of starting and performance issues in Ford S-Max engines. Make sure they are in good condition and replace if necessary.

I had a similar issue with my Ford S-Max and it turned out to be a faulty fuel pump. It's always a good idea to have it checked if you're experiencing engine problems.

Another common issue with Ford S-Max engines is the Mass Airflow Sensor (MAF). It can cause starting and performance issues, as well as decreased fuel efficiency. Have a mechanic check it and replace if needed.
