I have an 01 CTSC S2K with bolt on's running an 8psi pulley. A couple months ago in the summer I went for a cruise with 2 homies and the car would want to run at full throttle. I fixed that issue by replacing the spark plugs. About a week ago I got an engine light while cruising at night and my E-brake light also came on. I checked the code with a paper clip and it was the secondary o2 sensor. The CEL light in now off but the E-brake light is on. Now the car starts to bog out @ full throttle. Im confused.

Is there anything I can look out for on my AEM UEGO?

I had that happen when the honeycomb of my cat broke loose and decapitated an O2 sensor. Well, not the ebrake light but the bogging and CEL.

Do I replace the o2 or is it something else?
