What is the cause for my Vauxhall Astra's engine misfire?

I have a Vauxhall Astra that has recently started misfiring. It's a manual transmission and I'm not sure what could be causing the issue. I've checked the spark plugs and they seem fine. Any ideas on what could be causing this misfire?

One common cause for an engine misfire in a Vauxhall Astra is a faulty ignition coil. You should have this checked and replaced if necessary.

Another potential cause could be a clogged fuel injector. Have a mechanic inspect and clean the injectors to see if that solves the issue.

Sometimes a misfire can be caused by a low battery voltage. Check the battery and have it replaced if needed.

A damaged or worn out timing belt can also lead to engine misfires. Have the timing belt checked and replaced if necessary.
