Here are the most common problems,
Air leaks at the exhaust manifold or in the exhaust pipes. Catalytic converter is damaged, contaminated or has failed. Front HO2S or rear HO2S is contaminated with fuel or moisture.

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. Autozone turning the light off does nothing for you, and is against their company policy. If you do not have the proper tool, reference materials or experience I would take it to a professional. Finding out the trouble code is just he start of the diagnosis process.
