Vectra engine stalling and check engine light

I had something similar happen with my Vectra. Is your fuel efficiency also worse than usual? The light and the stalling could point to a problem with the fuel tank ventilation. It might be a faulty pressure sensor or even the purge valve sticking. Have you noticed any hissing sounds near the fuel tank?

Thanks! I haven't noticed any hissing, but fuel efficiency does seem a bit off. Where exactly is the purge valve located, and is it something I can check myself without special tools? Also, what was the exact problem with your car?

On mine, it turned out to be a defective activated charcoal filter causing a leak in the system. I didn't try to fix it myself as it's part of the whole emission control system, and I didn't want to mess anything up further. Based on your description, I would highly recommend taking it to a workshop. System failures like this can be tricky to diagnose without the right equipment.

Alright, thanks! I took it to a local garage, and it indeed was the activated charcoal filter! They replaced it for 275€, and now it runs smoothly. I appreciate your help!
