Chances are the EGR passages from the throttle body to the EGR valve are completely clogged with hard black carbon deposits.
The only real fix is to disassemble the throttle body & clean out the EGR passages. It's not a hard job, just takes a little time, patience, & 3 new gaskets. I did it yesterday on my '97 Expedition.
