check for codes first, then take your tune back to stock and then re load your custom tune and see if it comes back.

Thats the same code I have been getting but my car goes into failsafe mode also. I go WOT and the car reads failsafe mode and shuts off. Its the only code that I get now(before I had a whole list of them but I think I took care of the rest). Im taking mine tommorow to get serviced hopefully they will work on the car. At all other throttle positions the car is fine. I'll let you know what Ford says tommorow.

Check the throttle body. Just got back from Ford service and say everything was coming from the throttle body.
