What does this mean?

It means you have a current or stored fault. Do you have more of a story to go with this or are you just curious?

Charles, Did they clear the code? If not, I would try that first and see if it comes back. I am not a fan of the various additives to clean cats. They can make a bad situation worse or make a non-situation a bad one. If the CEL is persistent, you can have the cats inspected with a boroscope. This is all assuming you didn't hit something with the bottom of your car. If so, get to a shop right away. Physical damage to the cats can be very serious. How many miles are on the car?

They can, but often won't. You can get an inexpensive reader and do it yourself. Your O2 sensors shouldn't be bad at that mileage and it's odd for them to go out at the same time. Are you using quality gas?

You should plan on using premium EVERY time. These are high compression, high revving precision engines built to Maserati specs by Ferrari. It will run on less than premium, but it actually has to work at it. The engine parameters are designed for high octane fuel. When you run lower octane, it has to make changes to ignition, intake, fuel etc. to try to keep the engine from pinging or knocking. Losing power is the obvious side effect. Putting in crappy gas once in a while because you have no choice (for whatever reason) isn't going to hurt the engine. But I recommend not pushing it during those times. Putting crappy gas in on purpose, well, your car already told you it didn't like it and it didn't take long to do so.

lcdave....Could not agree more why would you choose to put regular in a car that is designed for premium. Let's say premium is an extra 30 cents per gallon if you put in 20 gallons of gas that is an extra $6.00. I would say that is the cheapest insurance policy to get the most performance from your vehicle and keep it running well. I would also recommend using Top Tier fuels that contain proper levels of detergents. Top Tier Gasoline

Welcome to MaseratiLife!
Without actually clearing the code with a scanner, it can take a few drive cycles to clear itself.
