Why is my Ford Focus constantly stalling during acceleration?

I have a Ford Focus with around 100k miles on it. Recently, I've noticed that the car constantly stalls during acceleration, specifically when going uphill. What could be causing this issue and how can I fix it?

It sounds like your fuel system may be clogged or dirty. Try using a fuel system cleaner to see if that helps. If the issue persists, it may be worth taking your car into a trusted mechanic for further inspection.

Have you checked your air filter? If it's dirty or clogged, it can cause issues with acceleration. Consider replacing it if necessary.

It could also be an issue with the ignition system or spark plugs. Consider getting those checked and replaced if needed.
