104,000 miles on the truck. It had been running a little rough since about 90,000. By rough I mean a slight miss at idle after the truck warmed up, longer crank time to start and some surging after letting off the go peddle. I got some stock injectors from gooseman495 (thanks Gooseman)and installed them this weekend. Truck runs just like new again. I just followed the write up at "http://www.dynomitediesel.com/user_pages/15_03-07_common_rail_instructions.shtml?page=Tech&subpag e=Common%20Rail%20Dodge%20Injector%20Instructions" and it went like clockwork. no special tools or gizmos needed. Thought I would let others know that it's not so difficult that you can't do it yourself.
