If the check engine light is on, definately get it read. If it is running rough and blowing smoke, along with knocking, I'd have it checked out by a mechanic. Their are a number of mechanical issues that could be going on, and if you are not mechanically inclined would run into more problems trying to fix yourself rather than just shelling out a little extra dough to have it done.
