Hey guys i own a 2000 v6 mustang convertible and strangely after driving over a brick today... my car started acting up i got a P0171 code and looked under the hood the only thing out of place that i could see would be whats in the photo. Its under the intake next to the exhaust manifold on the firewall i couldnt find a tube that plugs back into that hole and air is defintely coming out of it.i saw online someone with the same photo but there issue was different and it was never solved. Any help would be a appreciated.... What is that hole ???? And where could the line be ????
