Sounds like the problem I had with my 2001. If the code is for excessive egr flow, then all you need is a new pressure sensor (DPFE). It will be around $50 from any ford dealer. I got one for around $30 from genuine-ford-parts.com. I havent had a problem since i changed it and it took all of 3 minutes to change.
