Troubleshooting Engine Issues in the Ford Fiesta

I've been experiencing some engine issues in my Ford Fiesta and I'm not sure what's causing them. The engine is making strange noises and the car is losing power. How can I diagnose and fix these issues?

It sounds like there may be a problem with your car's spark plugs or ignition system. I would recommend taking it to a certified mechanic for a diagnostic test and repairs.

Check your car's air filter and replace it if it's dirty or clogged. A clogged air filter can reduce engine performance and cause strange noises.
