  • Code P0174

    So my engine light recently came on, got it scanned. Code P0174. Bad fuel/air ratio in left bank? The slip said something about the MAF sensor?

    Has anyone else thrown this code? If so what fixed it?
    2001 Firebird 3.8L

    inspect your vacuum hoses for splits or kinks, that the PCM grounds and sensor grounds are clean and in good working order. If that doesn't clear it, replace your o2 sensors
