I think i have a solution for you, I hope, for your sake. The other day I was bored, (this is going to sound really stupid) and I went under the hood of my C280 and I unplugged the wire that hooks onto the tube that comes from the air filter housing. I then started my car and it did the same thing as you've explained. It dropped real low, then popped up to 1500 RMP, never stalled though. So maybe your connection there is faulty? I am not sure if that's the Oxygen sensor, but it could be? HOpe this helps. Try and clean the connection and see if it helps.
