I have no codes and also had a live data scan done and everything appeared to be normal with my motor,, that is why I am leaning towards it's in the drive line somewhere and not fuel system, maybe like MOTOR MOUNTS, UNIVERSAL JOINTS,, OR THE DRIVE SHAFT CARRIER BEARINGS, because the way that it smooth's out while the truck is rolling weather I push it a slight bit in neutral or letting off the brake just a hair in gear D or R gears,, I have also just noticed that my pinion seal is leaking and not sure that would cause this vibration feeling idle only at a complete stop, I just can't believe how it just smooth's out as long as the truck is rolling ,what do you guys think,??


thanks
