Why is my Ford Fiesta running rough?

My Ford Fiesta has been running rough lately and I'm not sure what the problem could be. It seems to be struggling to maintain speed and the engine is making strange noises. What could be causing this?

It sounds like you may have a problem with your fuel system. Have you noticed any decrease in fuel efficiency or strange smells coming from your exhaust? It's best to take it to a mechanic to get it checked out.

I had a similar issue with my Ford Fiesta and it turned out to be a problem with the spark plugs. I would recommend getting those checked and replaced if necessary.

Make sure to regularly change your oil and air filter. A build up of dirt and debris can also cause your engine to run rough. If you haven't done so lately, it may be time for a tune up.
