How do I troubleshoot my Vauxhall Corsa's engine misfiring?

My Vauxhall Corsa's engine has started misfiring and I'm not sure what's causing it. I've checked the spark plugs and they seem to be fine. What else could be causing this issue and how can I fix it?

One possible cause of engine misfiring in a Vauxhall Corsa is a faulty fuel injector. Try cleaning or replacing the injectors to see if that solves the issue.

Another potential cause could be a problem with the ignition coil. If the coil is damaged or malfunctioning, it can result in engine misfiring. Consider checking and replacing the coil if necessary.

Make sure to also check the ignition timing and spark plug wires. If the timing is off or the wires are damaged, it can lead to engine misfiring. Adjust the timing if needed and replace any damaged wires.
