How to fix common issues with the Vauxhall Insignia's engine?

I bought a used Vauxhall Insignia and I'm experiencing some problems with the engine. The car is making strange noises and the engine light is on. What could be causing this and how can I fix it?

It sounds like you may have a faulty spark plug or ignition coil. You should take your car to a mechanic and have them inspect those components.

Another possible issue could be a clogged fuel filter. It's important to change your fuel filter regularly to avoid this problem.

It could also be a problem with the fuel injectors. They may need to be cleaned or replaced. I recommend taking your car to a reputable mechanic for this type of repair.
