Try unplugging the VCT solenoids and see if it smooths out.

Check the crankshaft endplay. Ford had a problem with the 2007s thrust bearings causing the crankshaft to walk back and forth.

If it's running worse, then I would be looking into timing/phasers. Broken chain guides and loose chains can cause the valve timing to be off more than the phasers can compensate for. Your codes state that the cam timing is off and it will misfire if it is.
