ES Engine Stalling

I'm at my wit's end with my 2007 Lexus ES with a gasoline engine! The check engine light is on, and the engine stalls at idle sometimes. I'm thinking it's the tank ventilation valve acting up. I suspect some hoses are clogged, messing with the pressure sensor. Has anyone else battled this emission system gremlin?

I had a similar issue with my ES. Check the purge valve and associated hoses. Could be a vacuum leak throwing things off.

Was it the same symptoms? Engine light plus stalling? And did you end up replacing the valve itself, or just cleaning the hoses?

Yep, same symptoms. I ended up just taking it to a workshop. They sorted it out quickly, so probably best to just get it checked.

Thanks! I took your advice and brought it in. Turns out it was the ventilation valve and a few cracked hoses. 175€ later and she's purring like a kitten again. Appreciate the help!
