How do I improve the acceleration of my Ford Focus?

I have been struggling with the slow acceleration of my Ford Focus. It takes me longer to reach desired speeds and merge onto highways. What can I do to improve the acceleration of my car?

One easy way is to replace your air filter. A dirty air filter can restrict air flow to the engine and decrease acceleration.

You could also try using a fuel injector cleaner. Over time, deposits can build up in the fuel system and affect performance.

Another option is to check your spark plugs. Worn out or dirty spark plugs can cause misfiring and decrease acceleration.
