2016 Mustang Ecoboost 2.3L 128k miles. I am the original owner and it is extremely well maintained.

Driving home the other night while waiting at a red light I could hear it sputtering. After turning the corner, I pulled into a parking lot right as it died. I wait a couple minutes and was able to drive home normally. No codes or warning lights.

Took it to a mechanic today with no success. Without codes, they say they cannot do anything.

From experience, I am 99% sure it is the evap purge valve or the low pressure fuel sensor. Is there anything I can do, short of changing those parts myself? I am afraid it will die in traffic and/or leave me stranded while I'm waiting for it to throw a code. Will any mechanic touch it with no codes? I don't have the tools/space/garage/time to diy.

How's your coolant level? Didn't the 2.3L have problems with head gasket failures?

Lots of issues on this year 2.3L. However, mine has been well maintained (and not abused). Coolant level is fine. Car has never overheated and coolant was flushed at 100k miles.

Maybe you could try putting an OBDII that records certain past X minutes so if/when it dies you have the sensor logs. I assume evap, fuel, air, etc should do it?

ETA basically a car Black Box ha

I understand…but took it to a mechanic today immediately after the stall and there were no codes. While I have my own reader I doubt it would be different.

I would change the evap purge valve and clean the throttle body. Odds are one of those two things is your problem.

This probably isn't helpful, but had the same symptoms twice in two different vehicles. One was bad gas and the other was a bad ignition coil. Surprised neither threw a code either time.
