Search the forums here, that seems to just be a feature of the cats used in the 4th gen, regardless of engine. Many people reported it when these trucks were new, and many people are still noticing it years down the line.

Yes kind of. But it only happens when I go up this one hill near my house that probably has a 250-300’ change in elevation. I try to be gentle when accelerating and get decent gas mileage (usually around 21 mpg). I read somewhere that a “bad” catalytic converter can decrease fuel efficiency which I have noticed a bit. I want to drive it to my trusted car tech, but he’s over 200 miles away and I’m not sure my car will make it there safely.
