P0420 / P0430 codes

[Crazyhorse1962]

Good Morning
Got a check engine light on my 2008 Jeep Wrangler with codes
P0420 threshold bank 1
P0430 threshold bank 2
Catalyst system below threshold
What would you suggest to isolate hoping it's not the converters thought about running a bottle of Cataclean has anyone had luck with this product
V6 3.8 169000 miles still running great no other issues
Thanks for your response

You'd probably have better luck on a forum that focuses on JKs. This one is for JLs.

I would dump some of this in the tank and follow the instructions. It has cleared up my codes.

There are many products that do this. I have used the Duralube on too.

It seems like I would drive it about 20 or 30 miles and the check engine light would turn off. I know that one time, I used the taser to clear the code and it did not come back on for a long time.
