Check engine light just came on...
I had a similar issue with my check engine light, but it was for my secondary cats. Apparently my O2 sensor after the cats were going bad. The way they could tell was by checking the voltage of the O2 sensors and they would not respond at all some times. Check both your cats and if it's not your cats, then more than likely it's your O2 sensors.
