Autofanatic Posted September 20, 2006 Share Posted September 20, 2006 I need some help here guys. ive done a search and nothing seems similar to my problem. Every once in a while, when I start my 1998 LS400 w/146K, the engine will vibrate quite bad and will last for several minutes on the road..usually smoothing out. My BEST guess (from what it feels/sounds like) is that the engine is running on an odd number of cylinders .... what would cause this????
