I'm going to be picking up a 2012 EcoBoost Fx4 this afternoon for an "extended" test drive... I want to see if it suffers from the rattle at cold start tomorrow morning... Anyhow, I've got a ScanGage II and was wondering what info I might look for if I plug it in to watch for any trouble spots? Thanks for any thoughts!!

 

Nothing too specific. Operating temps should be around the 200 range. IAT temps at least for mine at speed are usually a few degrees higher than the ambient air temp. I am sure others will chime in.
