How to fix a faulty engine in a Vauxhall Astra?

My Vauxhall Astra's engine has been making strange noises and not performing as well as it used to. What could be the issue and how can I fix it?

It sounds like your engine may be experiencing an issue with its valves or sensors. These could be faulty and in need of replacement. I recommend taking your car to a trusted mechanic for a diagnostic test to pinpoint the exact issue and get it fixed as soon as possible.

Another possible issue could be with your spark plugs. These can get worn out over time and affect the performance of your engine. I suggest getting them checked and replaced if necessary.

You could also try giving your car a tune-up to improve its overall performance. This includes changing the oil, filters, and other essential fluids. I recommend doing this regularly to keep your car running smoothly.
