One of your Cobalt's primary selling points is its economy and value.

Cobalt oxygen sensors send information to your engine's computer that indicates whether the amount of oxygen being mixed with the fuel is correct. This isn't constant thanks to outside conditions like air temperature, altitude and barometric pressure, and internal issues that include the load on the engine and the temperature. If you notice you're losing miles per gallon, check your O2 sensor for Chevrolet Cobalt, and then visit AutoZone for a replacement.
