The link I posted! It has seamed to work!! No problems no issues!! I took it away from the dealership. They give me the got damn run arounds 24/7! Took it to another local guy.
Im having this exact issue. Can't find any answers. Scared to death to drive my new truck. I traded off a 2005 duramax to get a truck I wouldn't have to working on every single weekend and dumping money into. Now this came up. Did you ever find an answer as to what it was?
