thank you, heyyou atleast no power when not running is normal and no shorts anywhre else

 

no new codes and had 51 psi at idle according to specs it should be 49 plus or minus 5 so that ok, i'm gunna do a compression check see what i come up with

 

compression avg 115lbs 107lbs was the lowest

 

thank you everyone for your help, i finally found the problem, i started taking a plug wire off one at a time and putting a plug in it starting the engine and checking for spark no 4 cylinder was dead, who ever would've guessed a new plug wire would be bad. i guess that why it was only really noticeable at higher speeds about the time the truck would shift. i do believe the coil needed to be changed also as the truck now runs much smoother then before and starts ten times easier.
