On every vehicle that this has happened to I tried a write entire as well.
The only time I've seen the issue go away was on ANOTHER Edelbrock truck.
But no tune changes were made. It seems like it randomly went away after a flash.
I always use the F150 Flex Fuel tables and 99/100 times it works, but randomly I'll get a Mustang/F150 behave like we're describing. I'll end up flashing the car/truck countless times with no luck, and I end up having to send the customer off with a 91/93 tune.
I'd like to pinpoint this issue.
