As I tried to pass a semi on the freeway just 20 minutes ago, I saw all this, either white or light blue smoke coming out from underneath my car. I have cutoffs. I floored it again, and again, it did it. As I came to a stop, I put in park and revved it up to about 5000 and no smoke at all. As the car was rolling, I put in N and rompped it and no smoke again. I then decided to run it, from 1st to 3rd at WOT, and there it was again. What is going on? I really don't hope water is going into my engine. Help me out, please.
