How to troubleshoot engine misfire in Vauxhall Astra?

I have been experiencing an engine misfire issue in my Vauxhall Astra and it is causing hesitation and loss of power while driving. What could be causing this problem and how can I fix it?

The most common cause of engine misfires in Vauxhall Astra is a faulty ignition coil. I would suggest getting it checked and replaced if needed.

Another possible cause could be a clogged fuel filter. I recommend replacing the fuel filter and also checking the spark plugs for any damage or wear.

Have you checked the fuel injectors? They could be dirty or malfunctioning causing the misfire. Try using a fuel injector cleaner to see if it helps.
