2006 Town and Country with 3.8 liter V6

Thanks in advance.
Running Problem. No Power, Sluggish, Jerks
Check engine light on. Scanned for codes. PO404 (EGR Efficiency).
Also road tested the vehicle.
Sluggish above 2,000 rpm.
Installed new electric EGR valve.
Replaced spark plugs and wires.
Ohmed coil pack. (Good)
Checked fuel pressure. 57psi
Cleaned the Throttle Body.
Cleared code and road tested it. Same problem.
Disconnected Catalytic Convertor, tied it over and road tested it.
It runs good as long as you are going at a steady speed or slightly accelerating.
But, if you slightly let off the accelerator pedal, it will miss and jerk.
Rescanned and it has a different code. PO300 (Random misfire).
All parameters on scanner show normal.
Any suggestions?

Thanks,
