How do I troubleshoot my Ford Mondeo's engine misfire?

I've been experiencing random engine misfires in my Ford Mondeo. What could be causing this and what steps can I take to fix it?

A potential cause for engine misfires in a Ford Mondeo could be faulty spark plugs or ignition coils. I recommend checking and replacing these components if necessary. Also, make sure to check for any vacuum leaks.

Another common cause for engine misfires in a Ford Mondeo is a dirty or clogged fuel injector. Try using a fuel injector cleaner to see if it improves the performance. If not, it may be necessary to replace the fuel injector.

In some cases, a faulty engine control module (ECM) can cause engine misfires. I recommend getting the ECM scanned for any error codes and potentially replacing it if necessary.
