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

I've noticed that my Vauxhall Corsa's engine has been misfiring, causing a loss of power and strange noises. What could be causing this issue?

First, check your spark plugs to see if they need to be replaced. If they are fine, then it could be a problem with the ignition coil or fuel injectors.

Another possible cause could be a clogged fuel filter. Try replacing it and see if that resolves the issue.

You may also want to check the air filter and make sure it's clean. A dirty air filter can cause engine misfires.

If none of these solutions work, it's best to take your Vauxhall Corsa to a certified mechanic for further diagnosis and repairs.
