Hello,
New to the forum andI have the same problem with my 2015 Titanium Ecoboost approx 50K Miles. I have CEL on, P1450 error code, Hard Starting/Stalling after refueling. I have already replaced the Purge valve with a new OEM part and cleared the P1450 Code.
I took the car and topped up the fuel tank and it was still hard to start and stalling. The CEL and P1450 returned on the drive home.
Any suggestions?
