How to troubleshoot a faulty engine in Vauxhall Combo Life?

My Vauxhall Combo Life's engine is acting up and I'm not sure what the problem is. It's making strange noises and the performance seems to be affected. What could be causing this and how can I fix it?

It sounds like your engine could be misfiring. This could be due to a number of reasons such as a faulty spark plug or a clogged fuel filter. I would suggest taking your car to a trusted mechanic to diagnose the issue and replace any faulty parts.

Another possibility is that there is an issue with the fuel injectors. These can become dirty or clogged over time, affecting the fuel delivery to the engine. You can try using a fuel injector cleaner to see if that improves the performance, but if not, it's best to have a professional take a look.

It's also worth checking the air filter and ensuring it's clean and free of debris. A clogged air filter can also affect engine performance. If it's dirty, you can easily replace it yourself or have it done during your next oil change.
