after reading that, I'm going to stop worrying about the code

hopefully it'll just disappear lol

I just clear it with my scan gauge

Told ya so :-)

You might want to fix the issue.

some people have had the code appear without any problems. sometimes installing headers is what causes the code.

Here is my POV on the code. It can be caused by headers moving it further away from the exhaust ports, it can be caused by a "race" o2 sensor, it can be caused by exhaust leaks.... Check with a scantool that the o2 sensor is bouncing up and down between 200 and 800mv or something similar. If its bouncing then ignore it / tune the code out. If you have a wideband just verify the car is bouncing the afr somewhere between 14 and 15.5 afr. I have leaky ass headers and a "race" o2 sensor and I get the code every once in a while. I just turned off the cel for it. Life is good afterwards. I cant stand lights on the dash.
