Default 04 Concorde 3.5L won't rev past 2300, p0016 and P0300

2004 Chrysler Concorde with 3.5L V-6. Will not rev past 2450, does not matter in drive or Neutral/Cold or hot. Throwing codes P0016 Cam/Crank position Correlation Sensor A-Bank 1 and code P0300 - Random/Multiple Cyl. Misfire detected.

Recent work: Thermostat replaced, Fuel Injector Cleaner for three tanks of gas, two new O2 sensors, New Crank and New Cam position sensors installed.

Tests: Fuel Pressure is solid at 60PSI. Spec is 53-63. Running and not.

When the engine gets to 2450 rpm in starts a violent fluctuation that jerks the car. It feels like you are pumping the throttle.
Scan tool observations: Fuel system 1 and 2 closed during idle and up to when the surging starts approximately 2400-2500 rpm. When the surging starts one and then both change to open. The engine is still running just surging.

The o2 sensors' readings are erratic.

The readings from the RPM sensors are very close to each other. I think them reliable.

MAP reading seems reliable.

Coolant Temp. seems reliable.

Ignition timing advances smoothly with engine speed up to the trouble speed. It seems to max out around 40 degrees. Then with increasing pedal position, the advance falls off until, at full throttle, the advance is around 22 degrees. At idle the advance shows 10 degrees.

I have no advanced tools such as oscilloscopes and such. I have an OBD-II code scanner. Any help would be greatly appreciated.
