So, I think my Foci is running rich, too rich I think. I'll start the car walk behind it and all I can smell is gas. Now I know what your thinking, the gas tank is at the back, and thats what I'm smelling. No it has the exhaust smell but with a robust addition of gas. I'm running a Cat-back exhaust, cold air intake, a header, and underdrive pullies, and Focus Sports spark plug wires.
What can I check, I just changed the spark plugs, I gapped them to 0.050". I wasn't sure, other than that, I'm pretty much lost

Check to see if your rocker cover gasket is toast. I know there is a big difference in fuel smell and oil smell, but you never know.
