I have an 01 5.4lt in Phialadelphia with the same issues, I'm ready to drive it through a wall. I've cleaned my MAF and throttle body a few times and it always comes back on after about 60 miles.
PCV rotted tube
Now, I am hearing by a lot of people that its the PCV tube. If you search google people say its a Ford part number and its the elbow BEHIND the throttle body that is very hard to see. I guess it dry rots and that is the main cause for these codes. It is a B**CH to get to that's why I haven't replaced mine yet. I don't know how people change it but I will eventually do it once it gets warm here in NH.
