Please Help at Whits END!!

I have a 95 F350 Crew cab 5.8 (H)code engine
What its doing is missing at speed, lacks power, idle's rough, wont pull itself out of paper bag. NO CHECK ENGINE LIGHT AND NO CODES

What i have done in the last year
Remanufactured long block 08/10
Battery and alternator
plugs
pcv
verified fuel pressure
fuel filter
swaped out to verify ignition controller and coil
Tps switch
distributor
cap rotor and wires
verified that cats are not pluged up

I know this has to have happened to someone else

You put the remanufactured long block in about 6 months ago. How many miles on the remaned long block? At what point did your problem begin?

I would consider checking the rocker arm to valve stem clearance. Unless you get some easier to try suggestions first.

do you a MAP or a MAF sensor?

95 is probably a MAF check it. my f250 had similar problems and a mechanic told me to check that out. EGR also could cause some of the symptoms.

It could be as simple as a fusable link, i had bought a ford ranger with one it did exactly what your saying, my mechanic found it and removed it some one jimmy rigged teh fuse box with a paperclip.
