problem while driving? not sure what it is
Ever since i got my truck, when the engine was cold, i would take off and as the truck shifts, the rpm drops tremendously and then immediately picks up again... as a result from this, there is some sort of vibration in the truck and i have no idea where its coming from...
I have a 2006 5.4L SuperCrew with about 130k miles on it
