Hi Scotty, I have a Cadillac SRX 2011 with a 3.0 engine. The vehicle is sputtering when it's running idle and when I press the gas it starts sputtering. Is this a bad O2 sensor?

How old are the air and fuel filters? Spark plugs? Any vacuum leaks? Fuel pressure OK? It would be a good idea to perform a diagnostic scan for codes and data.
@chucktobias Air filter and spark plugs are new. The fuel filter has not been changed though.
@bb-h Check fuel pressure and for vacuum leaks. If that's all OK scan for codes and check live data for clues to what's causing the problem.
