Initially, what you described sounded like surge. Now it just sounds like a delayed closed-loop with temp probably has fuel trims compensating for vacuum leaks...

(If it did not do it beforehand, then it is obvious what caused the issue)

Agreed, didn’t do this before and now it does. Drained rad and new coolant, temp gauge is fine, needle is dead middle. It just really weird, only does it when I guess it’s “not warmed up” but after hittin the throttle after a while it just goes away very weird

Not weird. It is exactly what I just described above. Open-loop to closed-loop with vacuum leaks.

Air and fuel are whack along with possible random misfire.
