Common Issues with the Ford Focus Engine

I have noticed some problems with my Ford Focus engine lately. It seems to be running rough and I'm worried it might be a serious issue. What could be causing this and what steps should I take to address it?

It sounds like your engine could be misfiring. This could be caused by a variety of issues, such as faulty spark plugs or a clogged fuel injector. I would suggest taking your car to a trusted mechanic for a diagnostic test to pinpoint the exact issue. This will prevent any potential damage to your engine and save you money in the long run.

Another possibility is that your air filter is dirty or clogged. This can restrict the air flow to your engine and cause it to run rough. Check your air filter and replace it if necessary. It's a quick and inexpensive fix that could solve your issue.

Make sure to also check your oil level and quality. Low or dirty oil can also affect engine performance. If it's been a while since your last oil change, it's a good idea to get one done and see if it improves the engine's performance.
