1996 Cadillac Deville, 2004 Cadillac DTS, 2011 CTS AWD Coupe
So, basically my first car...and being winter, Im not too sure what is normal. Its around 50 out here...and my car is a smokin! When I start, even after driving, especially when idling after driving, huge clouds of smoke come out of the tail pipes. I mean, its a lot, I dont know if anyone else has this much, but its like big, heavy smoke that travels. I also think it has a sweet smell to it but I havnt noticed any performance drops or any excessive drops in the coolant. What is normal? P.S about 3 months ago, it over heated- no problems since then. So guys, any ideas? Thank you!
