So I have a sputtering problem like when driving it kinda seems like it loses power quickly then comes back and it gets really bad when I excellerate it kinda throws the car back and forth

What is your question?

So the problem happens all the time even when ideling it doesn't rev up it drops in rpms almost a full 1000 rpm and when I'm excelerating it gets a lot worse.

What makes this problem better or worse?

Worse when the engine warms up

How long has your 1991 Nissan Pathfinder had this problem?

Almost 3 months
