I own a 1993 F350 4WD cab and chassis flatbed with a 7.3 IDI and 5 speed transmission.The truck has 191K miles and it struggles to do 55-60 mph uploaded. I have changed fuel filters,resealed fuel rails, air filter, new exhaust ( factory ), New CDR valve and tank selector valve. I've swapped the mechanical fuel pump to electric. I am absolutely sure i do not have any fuel delivery issues to the injector pump. The truck starts great when cold, good oil pressure and no abnormal rattling.
Anyone have any thoughts?
