Car Can't "find" Idle

[angusis2fast4u]

When i start my car it doesn't seem to be able to "find" idle like it will jump between 800-1000 rpm and just go up and down, From memory it only happens when the car is cold or warming up. Also sometimes when i push in the clutch to slow down (i.e. slowing down to stop at lights) the car seems like it wants to die (it will fall to like 200rpm) but then goes back up to normal idle.

I know this has probably been answered before but i haven't really found anything directly related to this.

check for vac leaks

check TPS voltage

clean afm

clean AAC valve

^ as above. Most likely AAC or VAC leak.

If not try disconnect the factory o2 and see if it stops
