Help me please, my Idle's gone crazy

It goes up to about 1250, then almost cuts out, and drops to 750, then it rises to 1250 then almost cuts out and goes to 750.......
It just randomly started this today when I came out from the bank. Also, turning the AC on slows the cycle, but it cycles the same nonetheless. Any ideas on what might be causing this/ how could I fix it?

Mine did just about the same thing, but the idle evened out sometimes after the motor warmed up. It ended up being the ISV. Try disconnecting the ISV with the IGNITION OFF...start her up and see if it's any better.
