at cylinder misfire counts,egr,O2 sensors,fuel trim &

Might want to check to see if you have a bent rim or a bad tire.

SOURCE: Maybe a transmission problem?
If you're only in "D", you should switch to "OD" when driving at higher speeds. "D" only allows you to move up to third gear whereas "OD" will move you into fourth. You're over-working your transmission by driving in "D".

In addition to the above, also try cleaning the Mass Air Sensor. it is located just past your air cleaner going back towards the engine. Just unscrew the to star bolts and you will see a small fillament when you remove the sensor. If it is not shinney and appears dirty, give it a qiuck blast of carb cleaner and then let it dry for a minute. Put the sensor and bolts back in and see if that helps. I have used this on two Ford Ranges and an Explorer. Seems to help a rough running older engine.

The trans is controlled by the computer. There should be something that a scanner will tell you if you have it scanned. It is good that the rpm's are staying steady. You may have a drivablity problem that is showing up while it is in lock up mode. This will amplify a miss in the engine. The 5.4 is a motor that few tune up because of how hard it is to replace the back four plugs. Try a good tune up and fuel injection cleaning if there are no codes in the computer to indicate another problem.
