How do I troubleshoot engine idle issues on my Vauxhall Corsa?

I noticed that my Vauxhall Corsa's engine idles rough and sometimes stalls. What could be causing this issue and how can I fix it?

One common cause for engine idle issues is a dirty or faulty idle air control valve. You can try cleaning it with specialized cleaner or replacing it.

Another possibility is a vacuum leak. Check all hoses and connections for cracks or leaks and replace as needed.

Low fuel pressure can also cause engine idle issues. Have your fuel pump and filter checked to ensure they are functioning properly.

It's also important to regularly clean or replace your air filter and spark plugs to maintain proper engine performance.
