Car threw a P0430 today, I did a search and people say 90% chance it is the cat conv. Now I can take it to any GM dealer and it's covered as these have a warranty right? (8yr/80k regardless)

That's how it worked when I had a cat take a dump on me.

That just doesn't sound right does it?

More than likely it is the rear O2 sensors.

Yes it's the cat and yes they will replace it under the 8/80. We have had several of these come into the dealership including my car...it seems GM had a bad batch of cats..always sets a P0420 and always is the drivers side cat. The P0430 I dont see too often...cuz its usually the drivers side.

Wouldn't P0420 would be the drivers side cat, P0430 the passenger side?

Went to autozone and had them scan it. I have a list of things it 'could' be but I did a quick search here and people say more than likely it is the cat. I'm debating whether to put in some 02 sims, maybe that will fix the problem as yesterday I got a emmissions notice in the mail I plan on running LT headers with no cats, ORY in the near future and would need o2 sims regardless.

its the cat, same thing i had, if it was the rear o2, it would throw a bad rear o2 sensor .
