Why does my Vauxhall Crossland's engine keep stalling?

My Vauxhall Crossland often stalls while I'm driving, especially when I come to a stop or slow down. What could be causing this issue?

It's possible that there could be a problem with your fuel system. Check your fuel filter and make sure it's not clogged. If it is, replace it. Also, check your fuel pump and fuel injectors to see if they are functioning properly.

Another potential cause could be a faulty oxygen sensor. This sensor measures the amount of oxygen in the exhaust and helps regulate fuel flow. If it's not working correctly, it could cause the engine to stall.

If your engine is stalling when you come to a stop or slow down, it could also be due to a dirty or faulty idle control valve. This valve helps maintain a steady idle speed and if it's dirty or not working properly, it could lead to stalling.
