Default surging idle/clipping during acceleration

Howdy, well the car seems to be screwing up. At idle, it surges between 600'sh-800'sh. Also, under mild acceleration I can hear small blips in the exhaust, but it doesnt jerk as it its losing power, just changes tone in the exhaust. Whenever I hit OD and the low RPMS set in, if I go to give it a little gas, it starts getting choppy/cutting out and you can hear it in the exhaust. Then I'll bring it down to D and it'll clear out, still make the blip noises but it clears out. Seems to not like being under load at lower RPMs. It hasnt kicked a single code at me.

The only thing I've done to try and fix this, is block the EGR off, and also cap the small vacuum outlet on the drivers side of the intake (which was plumbed to a box that then went to the EGR). I was hoping the EGR was giving me issues, but now I'm not so sure. I kinda got on it and its goes nowhere. I guess it "could" be my tranny but it definitely seems like a motor issue. Any ideas?
