05 frontier v6 4x4.  when driving anywhere from 60 - 80 mph the truck will chug and spit and sputter. I can either let off or give it more gas and it will go away. If Im getting on it hard it doesnt chug at all but if im slowly working my way up to 60 it will do it evry time if I continue on at 60 it will just continue to chug. it seems to do this at 60 every time but happens at 70, 75. No lights have ever lighten up either to give a code. Ive done searches cant really find any similiar issue any help would be greatly appreciated.
