Oil leak and engine stalled

[Perrier]

Now then, ran out of ideas what to inspect next, so attempted to start the car. It started without much effort, lots of drama from smoke for about 10 minutes.

Car is running with the following problems:
1- idle rough. It sometimes dies when coming to a stop
2- power seems to be there
3- CEL is on
4- Traction control light was on but it turned off now. Possibly due to towing.
5- When driving it feels very rough, like a fouled up plug. I did put in new spark plugs before starting it up.

Where to now, St. Peter, for I am in your hands now?
