Hi, Just picked up a nice 2001 RAM 2500 2 wd Cummins 12 valve, auto transmission . On the way home I noticed at around 45mph it started bucking when I was just cruse in along and it lasted till 60mph. If on the throttle it won't buck at all , so I stopped and got some Lucis injector cleaner and lubricator stuff. Any Ideas as to whats going on? Please help! Thanks a lot!!
