How to troubleshoot a faulty engine in a Vauxhall Mokka?

I have noticed that the engine in my Vauxhall Mokka is running rough and making strange noises. What could be causing this and how can I fix it?

It is possible that your spark plugs are worn out. Try replacing them with new ones and see if that improves the engine's performance.

Another common issue is a clogged air filter. Check your air filter and if it looks dirty, replace it with a new one.

If neither of these solutions work, it may be a more serious issue with the engine. Take your car to a mechanic for a proper diagnosis and repair.
