So O2 sensors? What exhaust do you have? If you have a aftermarket steel exhaust that isn't as restricted that would probably be why... as heat will sit on steel longer and heat differently. Also will measure different due to high flow.
Just a thought really. Is there a fix? /shrug maybe if you flash your car. I know I wonder if I could find REVO near me I'd be able to get rid of my CEL by going to 2 or 2+
