Have you gotten any resolution on this issue.Mine is doing the same thing only worse. Do not switch to 93 octane as this issue only gets worse and still doesn’t give engine light.
Mine is going in this weekend with the blessing of Ford corporate to do diagnostics beyond the “ their is no code”.
Call (800) 392-3673 (be patient, they are nice but deal with a lot of jerks. Don’t be one) and get a ticket started. The more they hear about this the sooner it gets taken care of.
Mine will be in for a few days but I’ll post the findings. Good or bad.
? I have the exact problem since day one.
