My 2006 4 cylinder is throwing a code that the Autozone dude told me was a problem with the catalytic converter.

I've heard that the G6 has a problem with its Cat.

3 Main questions:

1. Is it bolt on or weld on?
2. Where can i buy one?
3. How long can i drive on it until my car will stop working all together?

Kinda both, it's part of thr down pipe and cat are one assembly but you can unbolt it from the header and the rest of the exhaust....
but....

Was it code P0420?

Most of the time when that code is on it turns out to be that O2 sensor. Replace the sensor (Post/After catalytic converter) and get the code cleared. If the light comes back on for the same code, then you will need to replace the catalytic converter. Good news is the if you are in the US. It will be covered under warranty for 8 yrs or 80,000 miles. Which ever occurs first.
I would also go to a GM dealer and buy a bottle for the fuel system cleaner to poor in

Unfortunately, I have 120,000 miles on it already.

I'll go by autozone again and have them test it to see which code that it throws.

would all code tester thingies show that code if it were the O2 sensor or throw the same code for the catalytic converter? Or do some just say "catalytic converter" or "O2 Sensor"?

They don't have the right tool to pull the code than.... when you go to the dealer you should get that number. Actually have them do it a good dealer should do it for free it's srsy takes Min's max

I'm having a little trouble understanding some of your responses. Are you typing on a cell phone or something? Not trying to be rude.... I just want to understand what you're saying....

Yeah I was :eek:, was it that bad?

Auto zone does not have the same tool as the Pontiac/gm/dealer. They have a dedicated tool that can pull more info and that code has a number as well.

What I'm saying is go in to your local dealer have them scan your car for codes(This should be free if they are a good dealer). and you will know what to look for then.But I'm certain that the sensor in your car has gone bad. Also if your cat was bad you wouldn't pass emissions, and you might be getting a rotten egg smell

Basically there is a tool, which they hookup to your car, which reads your car's computer for diagnostics. All of these tools should provide an error code (if a problem exists.) If it's a bad sensor (which was a problem for me before), its nothing troublesome... But yeah, call your dealership and have them read you the code and record it.

I actually bought one of those scanners, so I didn't have to deal with the dealership/mechanics.
