Got a SES (codes P0171 P0174) and long story short, had to replace my intake manifold gasket due to a vacuum leak. I thought the car ran pretty strong prior to the fix, given that it had over 100k before replacing the gaskets, but now it runs MUCH smoother and it seems a bit faster. Any idea how many horse I may have been down with the leak? Or is it just my imagination that it has more juice after the fix?
