so ill be going down the road and then the truck will stop alcelerating and giving it more throtle will do nothing, its like you unhooked the throtle you can put it right to the floor and theres nothing no change in rpms. so natruly i start slowing down and pull over and the truck has a terible idle it lopes like a mother till i shut it off or slowly the rpms will drop on each lope till it stalls. then you can restart it and go alittle longer and it may or may not do it again. i put a new cam sensor in 2 weeks ago and that helped for a little wile then it started doing it ago. if you have any ideas it would be helpfull.
