How to troubleshoot a rough idle in a Vauxhall Mokka?

I've been experiencing a rough idle in my Vauxhall Mokka and it's beginning to affect my driving experience. How can I diagnose and fix this issue?

First, check for any trouble codes using a diagnostic tool. If there are no codes present, clean the throttle body and idle air control valve. If the issue persists, you may need to replace these components.

Another possible cause of a rough idle could be a dirty or faulty mass airflow sensor. Try cleaning it with a specific MAF cleaner and see if that improves the idle.

It's also worth checking the spark plugs and ignition coils. Worn out or faulty spark plugs can cause a rough idle. If necessary, replace them with high-quality, OEM parts.
