...Control. What does it mean? I took it to Auto Zone so they can run a diagnostic test and P1146 Emission Control Came out and the worker didn't know what it meant.

what is the problem? Is there a warring light on? How is the car running? Sounds like you might have check engine light.Emission control, sounds like the secomdary air pump is siezed or just ont working, they can wear out also sometimes they suck up water and eventually fail. Secondary air pump is part of your emissins control helps regulate emissions along with your coverter and O2 sensor, O2 sensor usually creates a engine missfire in one or more cylinders and creates a rough idle sometime and may even stall. A bad coverter will rattle at engine idle and may even clog and then burst a hole in the side of it. So with that being said try your Secondary Air Pump.
