    So I finally upgrade to the j from the h a few months back and it's been amazing until
    Now drove the car last weekend and all was fine went to go out on Tuesday and the car didn't feel right on start up went to drive off and it stalled I've no power in the lower gears it seems like it just want to stall I've changed the spark plugs cheeked the coils and they seem fine so I got a mate to plug the car in and it came up with code po171 which is the maf sensor I ordered a new one fitted it today and still the same doesn't sound great too any advice would be appreciated. Thanks Rob

    That code indicates a lean condition, not necessarily due to MAF.
    First checks would be for vacuum leaks and leaks in the exhaust manifold area.
