How do I fix my Ford Focus's engine problems?

I've been experiencing issues with my Ford Focus's engine. It's been making strange noises and feels like it's struggling to accelerate. I've checked the oil and it's at the right level. I'm not sure what the problem is and how to fix it.

It sounds like your Ford Focus may have a problem with its fuel system. You may need to have the fuel injectors cleaned or replaced. I recommend taking it to a certified Ford mechanic for a thorough inspection and repair.

I had a similar issue with my Ford Focus and it turned out to be a faulty spark plug. Have your spark plugs checked and replaced if necessary. It's a relatively easy and inexpensive fix.
