Why is my Ford S-Max losing power while driving?

I've noticed that my Ford S-Max is losing power while driving, especially when going uphill. What could be causing this and how can I fix it?

It could be an issue with the fuel injectors or the fuel filter. I recommend getting those checked and replaced if needed.

Have you checked the spark plugs? They could be worn out and not providing enough spark to the engine. Try replacing them and see if that makes a difference.

Another possibility is a clogged air filter. This can restrict airflow to the engine and cause it to lose power. Check and replace the air filter if needed.
