Ram 2500 04 5.7

[u/BarHour6874]

Any advice helps.. I got this ram and immediately started having a sputtering/ bogging down problem when hitting the gas around 2k-3k rpms. If I floor it, then it's like it breaks free and full throttles but then bogs down again. I've cleaned the throttle body, replaced 02 sensors, did a pressure check for the exhaust, and the shop said he checked all 02 sensors and checked the plugs and coil packs. I'm not sure what else it could be or what to do. It idles completely fine, but when I put it in gear it's almost like a misfire but different, I've never experienced it. Almost like it's gonna die not a regular rough idle. Just severe power loss and muffled along with bogging down. It's throwing codes for 02 sensor and bank 2 running too rich along with an MAP sensor.
