Default Cats and O2s

So I have an 09 Saturn Outlook Ive replaced all three catalytic converters and all O2 sensors. When I get into bumper to bumper traffic that night or the next day I still am getting the p 420 code and p 430. I have replaced and fix cracks n leaks. I don't know what else can be the problem. It's been in the shop for a whole month as well when fixing and trouble shooting. Prior to fixing the cats /O2 it melted the air intake.

If there's a thread I missed with this issue please comment the link

Default Re: Cats and O2s

Welcome to SaturnFans, Erza Scarlet!

Since I'm not familiar with the 3.6L engine's potential or common issues I'll make some suggestions through other web page links:

For P0430
For P0420

Were either of these links of any help to you? Of course, the Outlook was a vehicular relative of the GMC Acadian and the Chevy Equinox. If there are useful owner's forums for those SUVs then answers could be found outside of SaturnFans.

Biden/Harris predictions, '21 -'25: weak economy; weakened military; increased terrorism; a greater RED CHINA. I fear that I will be correct. I'd rather be wrong.
