Have you checked into changing the throttle position sensor, you would have to change the entire throttle body because Ford changed it.
I will try to get video of what mines doing and post it here.....
Was the pulse from the EGR happening around 2-2300 rpms?
Mine runs great,once its rolling,but if I hammer the gas....bog than takes off.
