Hi Teresa, Depending on the color of any excessive smoke from the tail pipe a technician will check for different vehicle issues. Generally bluish colored smoke could be an oil consumption issue. White smoke could be a sign of engine coolant leaking inside engine combustion, and black smoke could mean too much fuel inside engine combustion. Good Luck.
