Check the codes again - this time properly - and none what so ever. And on top of that it has not happened since I first posted.

This leads me all to belweive that it was just some random under the hood something that got splashed with slush/water/whatever while driving.

Case closed???

 

I see this frequently when driving in a lot of rain in colder temps, and then stopping at a traffic light or something. I figure it's just steam venting from the engine compartment.

 

I get it too.....in the rain
