Default 6.0 stuttering

I'm not sure if this is the right thread for this question but I need help. I have a 2000 chevy 2500 2wd and lately it's been a dog. Sometimes it will run just fine, other times when I hit the gas it stutters and doesn't want to move along with idling way down (It does the same when switched to neutral) eventually after holding down the gas pedal for long enough it will get its head out of its *** and want to move. What can I do?

Smoke test or WD40 test to look for vacuum leaks would be a good starting point. Worth checking plugs and wires, even though you're not getting misfire codes.

I replaced the plugs with delcos about a year ago but idk how old the wires are. I was told that a dirty throttle body can cause that. If I decide to clean it should I pull it off or just hit it with some carb cleaner and a brass brush?

What you're describing is classic vacuum leak behavior, though. Very difficult to run on little to no throttle (due to unmetered air, and therefore, underfueling) and it runs good at high RPM, due to unmetered air being a trace amount compared to the open throttle body.

A simple pinched injector o ring can cause that

I'll have to look into it. I thought it was something in the transmission for a good while lol

Like I stated in my original post I'm not sure if this is the correct place for this post. Everyone has been trying to help me figure this out up until you. If you don't like it then don't read it. Have a nice night.

I'm not much help for that. I'm a M6 guy. I would think that's the torque converter locking mechanism, if a gun were to my head.
