I pulled the O2 sensor today. I was surprised, it came out very easily. Zip tied it out of the way, and went for a drive. Check engine light was on, and it did sound quite a bit louder.
It behaved the same on the highway. Drives great in every gear except o/d.
The bucking stops when I give it enough throttle to downshift.
The vehicle currently has copper Champion plugs and basic Duralast wires from Autozone. They have 10,000 miles on them. Would it be worth it to change them out?

Super new sounds like the exact problem I had

the reason i said this is because i have a similar problem as the op... and my cats gutted... truck runs fine but once it shifts to over drive and the rpms drop down between 1400 and 2000 i have to make it down shift to speed up or climb a slope. just giving it a little more gas the engine seems like it has a miss.... but dose it...? so its ether that or the trany just sucks. or its because i have 265 tires with 3.55s but idk
