it would be best if we knew what engine you have. I'm assuming it's a 3.0 and what codes did you come up with? it is common for the egr to be gunked up on the intake side like yours was, but I would also check the exhaust tube for blockage. if you can, just disconnect it and blow into it, you will be able to tell. this link may help you check your egr and dpfe systems Part 1 -How to Test the Ford EGR Valve and DPFE Sensor.
let us know if you get it fixed.
