What are some common problems with the Vauxhall Astra's engine?

I recently purchased a Vauxhall Astra and have noticed some issues with the engine. Can someone provide some insight into potential problems and how to address them?

One common issue with the Vauxhall Astra's engine is a faulty spark plug. This can cause the engine to misfire or not start at all. It's important to regularly check and replace spark plugs to avoid this problem.

Another possible issue is a clogged fuel filter. This can lead to decreased performance and difficulty starting the vehicle. Regularly changing the fuel filter can prevent this problem.

A failing oxygen sensor is also a common issue in the Vauxhall Astra. This can cause a decrease in fuel efficiency and increased emissions. It's important to address this issue promptly to avoid further damage to the engine.
