Idle Jumping

http://i161.photobucket.com/albums/t...psehfwwlwp.jpg

Can anyone tell me if this is still needed if I delete the EGR? I'm trying to figure out why my car's idle jumps between 500-1500 rpms until it gets warm then it just dies. It runs alright when I unplug the MAF so I thought it might be that but it didn't get better when I tried a different one. Also, runs alright when I unplug the TPS and again, new one didn't fix the problem.

im not all that familiar with the egr system but Maybe a vacuum leak somewhere?
