How to troubleshoot a faulty fuel injector in a Vauxhall Corsa?

I am noticing strange engine behavior in my Vauxhall Corsa, which I suspect could be due to a faulty fuel injector. How can I properly diagnose and fix this issue?

First, check for any codes in the engine control unit using a diagnostic scanner. If there is a code related to the fuel injector, then it is likely the culprit and should be replaced.

Another possible cause of a faulty fuel injector could be clogging or dirt buildup. Try using a fuel injector cleaner to see if it solves the issue. If not, then it is best to replace the injector.

A simple yet effective way to identify a faulty fuel injector is by listening to your engine. If you notice a clicking sound coming from the injector, then it is most likely damaged and needs to be replaced.
