Sometimes it will take awhile for the code to clear and the light to turn off, if you indeed fixed the problem. You may not have fixed the problem, and it may be something else in the emission control system. I'd recommend a professional diagnosis--if all is well, they can clear the trouble code at the shop and turn off the light.
