the impalas have a recall for chassis control module which controls the fuel contamination sensor and lift pump. on the side of the bank 2 cylinder head is a high pressure injection pump. now if the car is intermittent and stall driving , you need to call the dealer because there is an open recall that is for people who call in and complain of this it is not on abn open recall page .the chassis modules came from the factory with internal moissture damage.

Error Code P0179 is defined as Fuel Composition Sensor Circuit High Input. This means the PCM (powertrain control module, or also known as ECM or engine control module) has detected an abnormally high voltage from the fuel composition sensor (flex fuel sensor) or circuit.
