Hey guys i have a 2006 kia optima, and when idling for about 3-4 minutes white smoke starts to come out my tail pipe, or when im idling at a red light, but the car isnt over heating or losing any coolant. Does anyone think they might know what it is? ---

Any check engine lights or drive ability problems? ---

How long of trips/drives are you taking ? After driving for 1/2 hour or more, does it still have the white smoke? ---
