The code p2097 on a Chevy Malibu means that there is an issue with the post catalyst fuel system. More specifically it means that the fuel mixture reading from bank 1 is saying that it's too rich. This could be the result of a damaged o2 sensor so if You think the fuel system is fine then You should make an attempt to replace both oxygen sensors next. A new oxygen sensor for this vehicle will cost between $15 and $40 depending on if it's a generic one or an oem Chevy part.
