Havent had much time to mess around with the truck lately, but I believe i may have found the issue. In the picture, the lower number beside the word "Max" (589.3) is the temperature of the exhaust ENTERING the Catalytic converter and the top number (443.5) is EXITING it. So between the issues im having now ( No acceleration, sporadic RPM, rich smell, black smoke from exhaust) and the known issues i either had or created (misfires, wrong injectors)seems to me I killed my Cat and thats my issue.
