This may sound weird but I had a explorer doing the samething and it turned out to be an intake gasket. Just throwing it out there.

This is a thought. If it is showing lean condition, I would look in the area of the EGR valve. You said that it is new. I am thinking it's not opening or not opening enough. Look for vacuum leaks or the EGR ports are restricted. I had a fight with mine back in October with some of the same issues. My vacuum tubes looked good but they were leaking through the side wall. You can use carb cleaner to find vacuum leaks. The vacuum tube and fitting on the back of the passenger side is where I would start. Then move to the upper and lower intake.
Don't forget to disconnect the battery to reset the code if you have an engine light. It will take a drive cycle for it to check itself out.
If you search my name and threads you can follow rant when I had this issue. Warning I was not an English major in school. There is a lot of caveman speak in it.
Please keep us up to date.
