O2 Sensor Reset

I have the exact same problem, and it just started. (164k miles) I'm in a different situation since I'll be replacing the exhaust with a Hi-Flow Cat system. However if you grow tired of looking at the light, you can pop six screws in the console and pull out the instrumentation cluster and pull the Bulb... since you can't tell if there is something else going on or not anyway it shouldn't matter to pull the bulb. Regardless of what the manual says you DO NOT need to pull the steering wheel to get the cluster out, just the six screws and some fiddling to figure out the right way to get it out.
Good luck.
