I just wanted to post to see what everyone thinks i should check. I'm leaning towards the TPS, or a fuel issue.
Here is a video of what it does when the throttle is very slowly applied until all of a sudden it takes off. It acts just like a carb that its idle circuits are clogged up making it lean out.

Not shown in the video is when it is at idle and starts acting funny.It will idle fine for a little while and then just start to have a slight miss. The idle control opens (very noticable wistle in intake as its opening to correct for whatever is going on) It only does it now and then. I haven't had the engine in the jeep for long so i can't say on the history of how it drove before. I have the front O2 sensor installed, but the rear isn't yet as i just finished up the exhaust today and thats when it started to act funny.
So far the plan is to test the TPS, install the rear O2 sensor, and if that isn't the problem i'll have to check the fuel pressure. Am i missing anything? I may also pull the brake booster line and plug it to make sure its not getting a vacuum leak from the booster.
