I am trying to figure out what: Monitors not ready-(evap 02)code from emissions means

Hello, monitors being set is when the engine's computer needs to see how various components in the vehicle are operating, in an effort to set air, fuel, spark mixtures properly to create optimum performance and minimal emission output. It takes a certain amount and style of driving to accomplish this. See this article: https://repairpal.com/drive-cycle-issues It'll take some driving -- likely normal -- to get the last monitor set. Evaporative typically does not have to be completely set in many states, but O2 does have to be set.
