Greetings ford people....my EA has lost all grunt and it happened over night. After spending 100's of $$$ no one can tell me what is wrong with it. It runs as if the valve timing is out. On the dyno it appears lean down low. I have replaced the map sensor, computer, fuel pump and injectors none of which helped. The computer tells me its the map sensor but after try 3 I know it is not so. I have had ther head checked, compression is well within specks as is the fuel pressure....anyone had this happen before????
