Hey Scotty, I have an issue with my 04 Grand Cherokee Overland. It has the 4.7 HO v8. Lately when I start it up it idles very very rough. The whole truck shakes. It feels like it wants to stall but if I give it some gas and start driving it the shaking goes away. It has always had a rough idle that I can't figure out but now it's much worse. Any idea what could be causing this? I have looked at the motor while it's doing this and the motor shakes as well.
