Have a 04 1500 hemi. Love the truck. It has some mysterious issues. Sometimes there is coolant leaks, sometimes not. Clicking noise in dash while above 45 mph to 65 mph, sounds like a relay clicking on and off. CEL comes on occasionally, gives codes P300 and runs rough and very rich during idle at start up. Them CEL goes off and runs find after 5 or so times of operation. I'm thinking it's just haunted.
