What are the common causes of a rough idle in a Vauxhall Corsa?

I've been noticing a rough idle in my Vauxhall Corsa and I'm not sure what could be causing it. Can anyone offer some advice on what the common causes might be and how to fix them?

One possible cause could be a dirty or clogged air filter. I would recommend checking and replacing the air filter if it looks dirty.

Another potential cause could be an issue with the spark plugs. It's a good idea to check the spark plugs and replace them if necessary.

A malfunctioning oxygen sensor could also lead to a rough idle. I suggest getting it checked by a mechanic and replaced if needed.
