Why is my Vauxhall Zafira Life stalling at idle?

I recently purchased a used Vauxhall Zafira Life and have noticed that it sometimes stalls when idling at traffic lights or when maneuvering slowly. It seems to happen more often when the engine is cold. What could be causing this issue?

The most common reason for stalling at idle is a faulty idle air control valve. It controls the amount of air that enters the engine while idling, and if it malfunctions, it can cause stalling. Try cleaning or replacing the valve to see if it solves the issue.

Another possibility is a dirty or faulty mass airflow sensor. This sensor measures the amount of air entering the engine and helps determine the correct fuel-to-air ratio. If it is dirty or faulty, it can cause stalling. Try cleaning or replacing the sensor to see if it helps.

It could also be an issue with the fuel system, such as a clogged fuel filter or a weak fuel pump. If the engine is not getting enough fuel, it can lead to stalling. Consider having a mechanic inspect and clean or replace these components if necessary.
