My 2004 srt4 randomly started smoking not sure why and it happens at random times. The smoke does not have a specific smell to it def does not smell like oil or coolant more of like a plastic burning kind of smell but it is coming out of my exhaust anyone have a idea what it can be please help!!! At first thought it was my turbo but really not sure the smoke usually comes when u let off a few seconds later it doesn’t stay for that long maybe a minute and it’s gone I’m just really confused and lost because of the smell!
