Too much yard work today to work on the truck. But I'm thinking the problem might be more related to a sensor or EGR going bad. The truck ran fine the rest of the day and last night. It only has the sputtering/low power problem on a cold startup right now. I can't really see that being the converter. As for the smell, I'm lost on that as well. I did notice that my clutch master cylinder is down a little on fluid. And smelling the power steering fluid it was similar to the burning smell so I want to check the vacuum lines to see if one of the VSV valves is going bad and possible pulling fluid through something.
