Hi acura101,
Smoke under certain circumstances are normal but not if it smokes most of the time.
When weather is cold, some smoke would be visible from the exhaust, that is normal due to the damp atmosphere.
If the smoke is white and you have coolant losses and/or overheating issues, the smoke could indicate a bad head or gasket.
If the smoke is slightly grey in color, it is oil being burnt in the cylinders or getting yto the exhaust system.
If smoke is black, excessive fuel is getting to the cylinders and not being burnt completely.
