Could be a LOT of things. There are over a hundred codes that will set of a service engine soon light. Go get the car scanned to see what the code is, bring it back here, and we'll go from there. Without that, we have no way of knowing anything.

How do you expect that we can help you, without you providing some information. Currently your post says something along the lines of "my car runs badly, why?" It'* very tough to internet diagnose w/o some codes or information.
For all we know it'* your UIM that cracked and you are losing coolant. You don't mention what color the smoke is, what it smells like or anything of that nature. This makes it very tough to help you.
