Intermittent P0420 code
Have a 2006 SRX, v6, 184000 kms.on it (114330 miles) MIL comes on after code clear in 2-3 days of driving, Has P0420 code. I have access to a GM Tech-2 scan tool and some prior experience.
I have cleared the code and driven the car as normal for 2-3 hours while monitoring the o2 sensors (all 4) with no apparent out-of-range data from them at any speed/load.
Has anyone out there encountered this same or similar issue? What was the ultimate repair?
Thanks for your help.

Sounds to me like the right side converter is going bad.__________________________________________________ ________________
