Yes stop. I mentioned this because its how it happened to me and why I use the anti-fouler. I just looked up Nevada to see if they perform a tailpipe smog emission test. "Nevada uses On-Board Diagnostics (OBDII) Testing for 1996 and newer vehicles." Was all I could find, so I'm not sure if your state even checks tailpipe smog emissions. If they do, the results of the test should be on the inspection receipt. Those readings will tell you how efficient your cats and engine are performing. If your well within the range, the cats are fine and its as simple as putting the light out with an anti-fouler. If they don't perform tailpipe smog tests, the anti-fouler to put out the CEL is all you need.
