so I have an 05 1500 4.7. I noticed that when I came to a complete stop and went to accelerate , the truck Rpms would go up but the truck would crawl slowly. I would have to gradually build up speed . The plugs and coils have been changed. O2 and TPS sensors changed within the last year. Only code is a loose gas cap . The pipes that attach to the muffler were broken off at the muffler a few weeks ago , and I have a possible broken manifold bolt so I’m wondering if it’s a clogged catalytic converter ? Any help would be appreciated
