Replaced all 02 sensors then about a week later keep gettng p0430 code.
Figured I'd post on here to see if anyone did anything specific to remedy this problem?

Be careful of non-OEM Sensors and don't use Universal Sensors. I made that mistake only once, no money to be saved there.

You can try to put back the rear sensor(s) you took out, see if that fixes the p0430 code. The rear sensor(s) only needs to be replaced when a new code reveals a problem.

The upstream sensors live in a "dirtier" environment and can wear out/get Lazy. The rear ones have a cleaner environment if the Cats are good and usually last much longer.
