    HELP! 2002 GMC Yukon SLT Fuel sensor/ABS Brake light/ radio

    Hi, my 2002 GMC Yukon popped an engine light today and the codes were P0179 and P0178. Both have to do with the flex fuel Sensor, but I have no idea how to take it apart or test it. Any ideas? Also my ABS and Brake light came on simultaneously while driving, goes away when I restart the vehicle...
