Might be dirty injectors. Try some Berryman B-12 Chemtool. It can't hurt.
Did you use Mopar cam and crank sensors or "mystery brand"? There are posts of folks who tried "no-name" senors, still had problems, then used Mopar sensors and cured the problem.

P0300 - Multiple Cylinder Misfire Detected

Possible Causes:

1. Air leak in the intake manifold, or in the EGR or EVAP system
2. Base engine mechanical fault that affects two or more cylinders
3. Erratic or interrupted Crankshaft or Camshaft Sensor signals
4. Fuel delivery component fault that affects two or more cylinders - dirty or sticking fuel injector
5. Ignition system problem - coil or plug in two or more cylinders
6. Vehicle driven with low fuel pressure or while very low on fuel

I would suggest checking your fuel pressure first.
