My name is Steve, I have 2007 Dakota that is experiencing multi engine misfire on 2 cylinders per my scanner. I have had the truck at three dealership and no one has been able to tell me what the problem is or able to repair it. I am thinking it could be the ECM the truck has 150,000 miles on it, the problem only shows up in the summer when the heat gets above 80 degrees. Anyone have thoughts of what could be the problem?
