Hi All! I have a 2006 Ram with 5.7 Hemi. It is a beautiful truck and came with a factory red paint job that still looks like new. I had a head light problem that I was able to fix with information from another member. I also have a strange tachometer problem. Sometimes it works fine than it will over spin and start working counter clockwise from the post and when not accelerating it just rests on the back of the post. It seams if I hit passing gear at higher speeds it reverts to correct operation and than a few days or weeks later it starts working backwards. Does anyone know a fix for this? I thought it might be a loose wire but couldn't track one down.
