Anybody know where I should start?

Hi,
I don't know where you got the info to cycle the key to start the DME , but I think that's where your trouble lies.
I think it's another case of not allowing the ecu to run a drive cycle and relearn. Disconnect the Battery again and then reconnect it. Start the car and allow it to idle for 5 min., then take it for a drive at 30MPH for 5 min. and then 45 MPH for 5 min. then stop the motor. Wait a moment or two to restart and you should be OK. Hope this helps...
Happy Motoring!... Jim'99
