White smoke is an indication of coolant not a rich mixture.
Black smoke would indicate a rich mixture.
If white smoke is coming out the exhaust, that would indicate a blown head gasket, intake manifold gasket, cracked head etc.
If the car is equipped with DexCool, you may be able to get a free fix from GM. They recently settled a class action suit for gasket failure on most V6 engines.
