Remove the EGR valve and clean it with brake cleaner, get a new o-ring kit from Ford.. It is probably stuck and coaked with soot..

p0266: Cylinder 2 contribution balance
p0284: Cylinder 8 contribution balance
P0404: EGR control Circuit Range/Performance
P0528: Fan speed sensor circuit no signal
P2285: Injector control sensor circuit low

Can you describe how its running

Probably a combination of the EGR valve and FICM not working properly..

He said it starts hard sometimes runs rough and bucks and misses at certain speeds also
