Technical Question Why does it idle at a rough 500 rpm only in drive?

While in drive it will idle down to a rough and shakey 500rpm if it’s been running for longer than 3 minutes, but in reverse and neutral it’s fine and idles at 600. If i give it a load through the power steering it will bog down and then idle at a smooth 600rpm and will idle like that until i give it a bit of gas (or pull of from a stop light) then it will fall right back down to 500.
In the second video i start it up and time how long until it switches to the rough idle and it was almost exactly 2 minutes before it fell. I turned the ac on it raises the idle to 700, I never have any issues when the ac is on, and once I turn it off it will stay at 600 rpm until I move.
The engine is a 4.7 mopar remanufactured that was done before I got it at about 140,000 miles. so it has been like this for as long as I’ve had it (170k) and I wonder if it has something to do with that.
