Why is my Vauxhall Combo Life experiencing engine trouble?

I've noticed that my Vauxhall Combo Life's engine is making unusual noises and seems to be struggling. What could be causing this issue?

It's possible that your spark plugs need to be replaced. Over time, they can become worn and affect the performance of your engine.

Another potential issue could be a dirty air filter. If it's clogged, it can restrict airflow and cause your engine to work harder.

It's also worth checking your fuel filter. If it's dirty or clogged, it can prevent adequate fuel from reaching your engine.
