2008 CTS Cadillac 3.6 stick ,have 2 po430 code 02S and EVA, put a new cat on old one was empty checked every thing was told cat,out on new now has 2-430

Sounds like you need a reputable mechanic with a good code reader to check it out. It could be an O2Sensor, I would almost bet on that one, but could be many other sensors as well. O2 sensors emit low voltage signals and if one is weak or bad it will act like the Cat is bad. make sure the wires are plugged in all the way, possibly one is loose from when they installed the new cat. Hope this helps. Hard to diagnose with out the vehicle here to hook up my code reader to.

P2099 fault code

The most common concerns we have seen have been related to fuel injectors.
This should be caught on initial diagnosis for these codes.
Perform injector balance or AFIT test prior to going further.
Note: Fuel injector balance test not available on 2009 Acadia, Outlook, Enclave and Traverse.
If normal diagnostics does not lead to a resolution for this code, then look for a small leak in the exhaust, usually at the outlet to the engine converter.
This leak will allow air to be pulled into the exhaust and cause a false lean concern at the post O2 sensor.
To diagnose this leak we recommend applying air to the rear of the downstream converter or to the tail pipe on single systems @ 5psi to 8 psi.
Apply a soapy solution to the gasket areas and the O2 boss.
Leaks in these areas that will cause the code will be larger bubbles
