Hey guys wondering if you help me out. My truck started to smoke (light haze )from the exhaust. I can see it at night with a vehicle behind me with there head lights. While the truck is stopped in gear you can see smoke coming out the exhaust. As I drive it continues to come out. While in park I don't see any smoke. The truck is in normal op temp. I can't tell what color it is I have the smarty jr in level 3. Thanks

 

mines ben doing it for years and its stock. i think its because of the cat
