Peugeot 607 Engine Stalling

I had something similar happen with my 607. Is it throwing any specific codes related to the EVAP system or a pressure sensor? Could be a clogged hose.

Thanks for the quick response! I haven't checked the specific codes yet, but a clogged hose makes sense. Where should I start looking?

It was indeed a clogged hose that time. Honestly, given the symptoms and your suspicion about the tank ventilation, I'd suggest having a workshop take a look. They'll be able to diagnose it properly and save you some guesswork.

Just to let you know, you were spot on! Took it to the workshop, and it was indeed the tank ventilation valve, specifically a clogged hose. They replaced it, and the total cost was 175€. Thanks for pointing me in the right direction!
