2025 Ford Explorer ST engine dies as soon as I put in gear

[ExplorerSTBob]

2025 Ford Explorer with 3800 miles on it. Everything was running fine and right after I filled up with gas, I start the engine and put in in gear and the drive 1 foot and the engine dies. I start it back up and try again and again and same problem except it dies as soon as I put in gear forward or reverse.
I have no check engine light on but after plugging in my obd scanner I got a P161B code. Had it towed to the dealer and he said they didn't see that code. A few days later, they called and said it was purge valve issue.
Anyone else experience this issue? I am thinking about having a spare one handy in case this happens again. This is the first time in 40 years I have broken down and needed a tow. Other times my car was able to limp along to get somewhere.

Heard topping off the gas tank can cause issues with this.

Its kinda the new modern day Ford. The vehicles will just leave you stranded.

There has been a lot of folks who've experienced this issue.

Overfilling the gas tank can cause purge valve issues.

When the gas pump shuts off do not be tempted to put more in. I think with cars nowadays those purge valves are really sensitive, if ya want to add a few cents to make it even then go for it but I would not hold it down after it clicks off. I have been doing this since I got my 2025 and so far have not had any problems.

I always pull out the pump as soon as it shuts off. So I don't believe this was the case here. Also this would run fine in Park. I could rev it up and it never sounded rough.

There is always a chance the station you use is the issue. Not all pump nozzles are the same. It would be hard to tell is that is the issue.
