You will get the greasy build up on the throttle body because of the PCV system. Which hose is split? The PCV valve is behind the intake manifold which is why it costs so much to replace it. The PCV valve is very simple with not a lot to go wrong. Mine even held up to boost before I removed the system completely.

The hose that goes to the valve cover carries already metered air into the top of the motor and the air rejoins in the intake manifold so if your venting already metered air that could be playing into your bad mileage.

I would recommend the plugs (which you've done) and a fuel filter change. I have never got less than ~25 mpg since I started driving my first '05 Focus back in 2007. My ST even got over 30 mpg highway with the turbo on it.

I think my low has been around 23-24mpg...that would be in the dead of winter, 100% city driving getting stuck in traffic and playing in the snow.

How are your tires; do they look like they are wearing evenly, properly inflated and a good alignment? That can hurt mpg's a little bit as well. Something you can look at but i doubt it would be the main reason you are seeing such sub-par mpg's.

You need to run several tanks of gas and then see about getting a good baseline for mpgs.

The tires are basically brand new. When I first got the car they were all around 30 psi, now I have them all at 42 psi I believe (the tires say 44psi max).

The hose I noticed can be viewed through the opening through the intake manifold on the right side, behind the manifold. It connects to a black plastic piece at a 90* angle from the hose. I believe that is the PCV valve I am looking at. The hose appears to be completely collapsed and is split open like a hot dog on the top.

Is there a way to replace just the hose without removing everything else to get down in there? I also need to find a place to order the parts I need, because there is no way I am paying almost $500 to have someone else do the job.

You are correct, that is the PCV valve. If it is split your loosing already metered air after the MAF which could be playing into your bad gas mileage.

You have to remove the intake manifold to do any work on the valve or hose. I've done it twice by myself in less than 4 hours.

Tousely Ford Parts is the place to get OEM parts.

Another weekend of wrenching has started. haha
I decided to just buy the parts from the Ford dealer and swap the PCV hose and valve myself.

I just got the intake off.

I can see now why the inside of my throttle body looked the way it did. The last pic is all the garbage that drained out after I sprayed around the openings with some carb cleaner to loosen the gunk. There was some oil inside it too.

I am going to work this evening on cleaning everything up real good and probably not finish putting it back together until tomorrow morning rather than rush it.

Anyone have any recommendations on a good way to get all this cleaned off before I reassemble?
