Answer 1

P2269 Water in Fuel

It is the fuel compositon sensor that detects the amout of ethanol (flex fuel) . The fuel composition sensor needs to be tested . Its operating range is in hertz from 50HZ to 150 HZ. If this is exceeded you need to verify water in fuel ,If water was in the fuel the drivability would be hesitation and stalling out.and even a misfire in one  of the the fuel injectors,Fuel needs to be gathered out either by opening the fuel line and activating the fuel pump or by drawing it out from the fuel tank. .If it is verified there is no water in the fuel tank. The fuel composition sensor will need replacement.
