Weird fuel to airflow ratio, seems to be too rich

Just having what i think is a high fuel to airflow ratio, mt daughter got the
engine a bit wet when washing her 2005 escape, was missing for a while so i
changed plugs and coils, put a scanner on it and the mass air flow seemd to
not be putting out properly so changed the sensor.  problem is still there.  
It starts fine and then after its warm it is really muggy, cant get it to a high
rpm, and get weaker the longer you run it, which isnt much as i cant get
more than 1 mile
