I have a 2006 Honda Accord EX-L coupe. 3.0L V6 My issue is that sometimes on start up white steam comes out from exhaust pipe. Lasts about 15 secs clears up then doesn't do it again until couple of days later. Im beginning to worry, No check engine light, no coolant leaks or anything. It's about 75-90F in the morning so its not from the cold. Any comments on this issue? Thank You so much I will be taking it to get it checked out on friday but would love some advice on this.
