Why is my Vauxhall Astra stalling while idling?

I have noticed that my Vauxhall Astra stalls when I am idling, especially at stoplights. What could be the cause of this issue and how can I fix it?

This could be a sign of a dirty or faulty idle air control valve. I suggest cleaning or replacing it as a first step. Also, check your spark plugs and wires for any buildup or damage that could be affecting the engine's idle.

Another possible cause could be a clogged fuel filter or a weak fuel pump. Make sure to regularly replace your fuel filter and have your fuel pump checked by a mechanic. It is also important to use high-quality fuel for your car.

If your Vauxhall Astra has a manual transmission, the issue may be caused by a faulty clutch or transmission. I recommend taking it to a trusted mechanic for a thorough inspection and repair if needed.
