After Startup and a settled idle put the truck in gear and give the gas to go and the truck will stumble, hesitate, put-put can't get out of it's own way (best way I can describe it) then will clear out and all is fine. It did it about a month ago with a outdoor temp. in the teens.
Just wondering if anyone had a similar problem.
