I have a BA MKII 2005 XR6 T 240kw not modified. Since june of this year I have encountered a Throttle Interruption problem that occurrs without warning and with no common reason. Cold running, after 1hr of normal running, on a freeway, in the back streets. The only one aspect I can think as being common is excellerating but not hard excelleration. Ford have replace the Throttle Position sensor on both sides Pedal and engine and as of last week replaced the engine management unit. All under warranty thank goodness!!! It is still doing it. My local dealer has now run out of ideas. They can see the error codes in the "Black Box" but can't isolate the cause. Has anyone else had this problem and are able to share the solution. I have also had a new gear box Auto as well in Jan of 08. You might think I have a lemon but I still love the car. Luckily all of this work has been under warranty. Any advice welcome Birdman
