Engine idling rough.

Engine idling rough.
New to the forum here. Long time lover of the ranger. Recently hit +200k on the truck and decided to do an engine swap. Replaced the engine wit the same engine but with less mileage. Currently running but it ideals rough.
I currently have no errors codes. I have attached a short video showing the rough idle and engine shake. any help would be nice.

Then pull all the spark plugs and do a compression test(cold engine) to rule out mechanical issue first, otherwise you will be chasing your tail with spark or fuel issues
Used engines are a roll of the dice, even if warrantied, and "tested"
You need to do your own test for compression
Expected with 4.0l SOHC engine is 165+ PSI on both banks, the SOHC can lose compression on one bank because of timing chain issue
Once a compression issue is ruled out you can move on to spark or fuel issues, otherwise you will just be wasting time and money if it is a compression issue
