84300DT It was idleing for a good 20 min. Before we took it for a run it was up to temp. I think either the fuel or air filters were dirty or the egr was acting up. It started up and idled to well to have low compression. I am thinking about buying it. I will go and look at it tomarow, I want to check the floor pans for rust and drive and look over it one more time. I think I might offer him $1,300. It could be a good winter project. All of the basics seem solid. If I put maybe $1,500 into it I think I will have a solid car. thank you for the offer I will take you up on it Sunday. You can drive my Camry if you want. That way I will have a MB diesel for 3k instead of like 7k-8k for an SDL. I can spend the difference on fly rods and stocks!
