Well my wife came home, parked the car took out the key and car is still running. I disconnect the battery and the car is still running?!?!!! What the?!?! Yes with the battery disconnected the engine was still going, never seen that before! So I took the key and turned it to start the engine again, note I was not getting any power to dash lights, air conditioning etc. And yes it made my starter work and this killed the engine. I am concerned, do this a few more times and I will be buying a starter. Any ideas? need new ignition switch? ECU? any relays related to this problem? Any help before I take this to an independent and grab my ankles.

Thanks everyone!!!
