Any car that I have had, from a Honda Passport, to a T-Bird, has run pretty rough, and smoked after sitting for some time.

I was told that the smoke was from condensation and it's deposits burning off. The longer they sit, the more there is to burn off.

I imagine that every morning you see a little bit of "smoke" come out of your exhaust when you first start your car up. The increase is probably exponential each day, because the larger the deposits, the longer it takes for them to "burn off".

Just a theory, but kinda makes sense. Keep driving it, and see if it goes away.
