Truck was running rough barely going over 35. Rough idle and smell of gas.

Their is no check engine on. Did find an exhaust leak, the bolts to the exhaust broke, I hope this will do it. I can't run any codes right now. Seems like someone thought they needed the reader more than me. But it showed o2 sensor when I read the codes a few days ago. But I'm not sure if their bad.

Ok, don't replace the O2 sensors just yet, at least not until you can scan again. I hate when tools grow legs. I've painted most of my tools, even some of my snap-on stuff, bone white. I've never ran into anyone with white tools, and if I do, I'll paint mine pink or purple. Anyone can say what they want, but if I see my tools in another guys box, I know they belong to me. The exhaust leak will throw codes for the O2 sensors, and can make the engine run really rough, but I would not imagine the truck would be limited. My money is on catlytic convertex blockage, and I bet the reason this bolts broke was over pressure since one bank is flowing nicely and the other is being forced to pump air.
