I have never noticed it before but today I started my truck and moved it to the shop so I could put some lights on it. It set for about 4 hours and when I started it to move it back to the house it let out this big puff of white smoke. I couldn't tell if it had a blue tent or anything but any ideas what I could be? I know its hard to diagnose with little Info but I searched and came up with a possible leaky injector? It was about 54 degrees outside and pretty humid im hoping it was just condensation. Truck has 83k on it

 

50 degrees? just steam because it's cold. I wouldn't lose sleep over it. Happens 6 months a year in Canada!
