Well Iam pretty dang sure I fixed it now. Idid what you all said replaced the DPFE sensor that wasnt the problem, checked all vac lines they were good ,cleaned hoses out to DPFE reset computer light came back on after about 20 miles . Fiinally I dove into it removed the butterfly to throttlebody and there it was the 2 holes that come off the EGR valve and go into the throttlebody were completly clogged cleaned them out real good put all back together reset computer took it for a drive and holy moses what a differnce. I bought the truck a 97 f150 4.6 used with 100000 miles on it, it never had so much power as it does now accelerating is 100 times better .
thx you guys for all the tips couldnt have done with out all your help let alone save me one heck of lot $$$$$$$$:rocker:
