Also, long term fuel trim was in negative before changing the valve.

Thank you for that information. Based on my experience, this stalling condition is most likley caused by a bad or dirty throttle body. Both are very common. I would start by cleaning the throttle body and throttle plate first with some throttle body cleaner and a soft wire brush and driving it around for a bit so the computer can relearn the idle. If the problem persists, replace the throttle body.
