[QUOTE="BLACKJKU, post: 464033, member: 18221"] Could be a bad O2, or maybe the Cat is going bad that's what it does is checks to see how the Cat is doing. But you said that they were both the same temp so I'd think the Cat was good. I don't remember is both downstream the same PN? If so swap them and see if it follows the sensor. [/QUOTE]
