Truck seems to have normal power through the gears, but on the interstate, it wouldn't accelerate like normal. I could get to speed and maintain, but aggressive pedal would do nothing. No codes and no smoke. Any ideas?

 

Maybe bad fuel? did you just fill up? how many miles on the fuel filter?

Reckon you were right Bulabula... just changed out a 1 month old filter and she came back alive.
