2004 dodge durango multiple cylinder misifre

Question

FUEL PRESSURE IS GREAT. HAVE REPLACED THE PLUGS, COILS, CAM SHAFT POSITION SENSOR, CRANK SHAFT POSITION SENSOR AND THE JUST PUT NEW INJECTORS IN BECAUSE THE OLD ONES HAD MASSIVE CRACKS RUNNING UP AND DOWN THE BODIES. STILL HAS THE MULTIPLE MISSFIRE PROBLEM ONLY UNDER LOAD CONDITIONS. IDLES FINE AND WHEN IN PARK IT REVS ALL THE WAY TO THE LIMITER JUST FINE WITH NO MISFIRE. MY ONLY OTHER THOUGHT IS THAT THE COIL DRIVERS IN THE PCM COULD BE BAD?
