2004 Buick Century Question: drive cycle
Drive cycles are different for each car. Your car's computer checks the functionality of the emission system each time you start and drive your car but some systems like the evaporative emission control system and the catalytic converter require a certain amount of driving under certain conditions, speed and temperature changes. Just drive your car for a few weeks it will do the tests itself. - patrick mannion
