Check Engine Light On problems of the 2007 Ford Expedition

I have the 5. 4 engine in my 2007 Ford Expedition with only 70,000 miles which I purchased in 2007. I am now experiencing cam sensor problems, throttle body problems and need major repairs. I have visited many sites and understand that Ford has been sued because of complaints with this particular engine and nothing came from this suit. This started around 2-3 weeks ago, I had been traveling for 2-1/2 hours and just pulled off the highway to enter into my housing plan, when my car lost rpms, became very rough, and then stalled. When the vehicle is on open it road it rides great until you slow down and the rpm falls, then it stumbles and stalls. I had at the dealership a couple of times, but until check engine light came on, I could not get it diagnosed. Over the weekend the check engine light finally lite and as I stated it is the cam position senors and states that the systems too rich. I talked with a Ford rep today and this will be about a $2000 repair bill, but until I can get it to them and they place on their computer, they cannot give me their final estimate if it can be repaired or I need a new engine. I have many misgivings about this since all that I have read on the internet about all the problems with this particular engine. Ford should be held accountable for a faulty engine, and buyers should be made aware of this problem especially when they are buying a used vehicle from a Ford dealership who is definitely aware of this problem.

The contact owns a 2007 Ford Expedition. The contact stated that while driving at various speeds, the check engine warning light illuminated. The vehicle was taken to the dealer for diagnosis where it was stated that the catalytic converter needed to be replaced. The vehicle was not repaired and the manufacturer was notified. The approximate failure mileage was 90,000.
