OK, Here's the update.. . . .
Dealership called me back, and had preauthorized the repair. The car is now fixed and ready for pickup. Scary isn't it????
It was the air filter.
Yep-- that's right-- the air filter.
Thanks to Ford for only charging me $35.00 and writing off 6 hours of diagnostic time.
note to self-- next time, change the filter .. . .. .
