The '94 Cadillac Seville smokes badly when it sits idling for a few minutes or starting while hot. The problem is fuel leaking into the intake manifold from the fuel pressure regulator or a leaking injector. In this case there is gas sitting on the bottom of the manifold. It gets sucked up through those black intake pipes - of which most have been removed for the picture. The square holes are the air intake and the small round holes above them are where the fuel injectors go. The fuel pressure regulator is at the top of the picture.
