So my 06 dodge OS 11352407 has a really odd lope. It lopes when its cold out around -5C or colder, you start the truck and it idles at 1000rpm for a few min then it will start to get this were lope. It started this after we put a tunner in it a few years ago, it still did it when you went back to stock. I've tuned it now and it still does it. I just recently data logged it and the post feul and the main feul will drop to 0 intermitently when it lopes. I'm not sure what is causeing this. Has anyone else found the a solution? I have a few buddies trucks that have this same issuse, and in winter you hear it quite often when guys leave there trucks idleing in parking lots. I'll attach the log file.
