I checked my car for stored codes this morning and there was a P0430, "Catalyst System Efficiency Below Threshold (Bank 2)"
Car has off road X-pipe and welded in flowmaster. I guess the next step will be getting under it to see if it has MIL eliminators on the rear o2s. Also the check engine light doesn't come on when the key is in the "run" position like the rest of the lights on the cluster do. Is this something tha'ts only turned off with a tuner or can the bulb be removed? I'd like it to be functional. What would cause the car to show that code? Thanks
