Hey guys not sure if this is the right thread but I need help. I have a 2001 Dodge Ram 1500 5.9 Off road package 150,000 miles. About a month ago while driving between 40-50 and around 55 she started jumping. Cant tell if its the drivetrain or a fuel/ electrical problem. I did find a loose ground on the battery last week and thought for sure that fixed it, but shes still doing it. All fluid levels are good. tranny fluid/filter was replaced last year and is still pink with a hint of gray. I do plow occasionally with the truck, but not commercially. I thought about fuel filter replacement, but from the sounds of it there is no inline? plug wires are new and coil is a yr old also. Any input would be awesome. Thanks
