[QUOTE="rollingthunder, post: 335467, member: 1005"] key on and cranking it is at 48.5-49. Idling it jumps back and forth between 49 and 45. Cruising down the road at 70 it does the same. Only had the truck a month or so, but watching it before it never went below 48--stayed mostly at 49. Now it fluctuates back and forth. Just trying to make sure everything is tight on the truck before I leave for Omaha NE in 2 weeks. [/QUOTE]
