Why does my Vauxhall Astra keep stalling?

I've noticed that my Vauxhall Astra has been stalling frequently, especially when I'm stopped at a traffic light or in slow-moving traffic. What could be causing this and how can I fix it?

One of the common reasons for stalling in a Vauxhall Astra is a dirty or faulty idle air control valve. I would suggest getting it checked and cleaned or replaced if necessary.

Another possible cause could be a clogged fuel filter. It's recommended to replace the fuel filter every 30,000 miles, so if it has been a while since it was changed, it might be worth looking into.

Low engine oil levels can also lead to stalling in a Vauxhall Astra. Make sure to regularly check and top up your engine oil to prevent this issue.

If none of the above solutions work, it could be a problem with the ignition system. It's best to have a professional mechanic look at it and diagnose the issue.
