OBD Code

I have a 97 Grand Marquis and the OBD is giving P0171 and P0174 Bank 1 and 2 running lean. It burns gas like crazy and my uncle says its running rich and he hopes its not a bad intake gasket the manifold was just replaced because the old one cracked (stupid plastic) so he's hoping it isnt that and he told me to come on here and ask help and what anybody else thinks
