DC2 Idle Problem

[E=MC²]

Okay so ill explain the problem first. My car idles at 850. When i hi the gas to about 3k it drops to about 550 to 600 and jumps and studders. after about 30 sec it goes back to 850. when im driving i can run it to 8k let it drop and it will stay at 2k for about 30 sec before going back to 850. so i unplugged my tps to see if anything would happen. car runnings at 850 rpm and nothing happens at all. could that be the problem. im going to clean the iacv and the fitv and see if that makes a diff.

oh and if im at a red light and turn on my ac it dies. if im in a parking lot and i turn my wheels all the way it dies.
