98 4.0 idles fine but misses horribly under load

idles fine 90% of the time but when put in gear and push on the gas it sounds like it drops 2 cylinders and feels like it has a brake sticking. but if u ease very lightly on the gas it will run and shift like normal. if its on flat ground that is. have changed plugs and wires, fuel filter, maf, coil pack, throttle position sensor, ecu or ecm the one mounted in firewall at the top passenger side. checked fuel pressure at idle was 65lbs. seems quite high. have a code reader I used on it and many many codes came up. I wud say almost all sensors including ecu and all shift sensors. will get a complete list after lunch and post them. am leaning toward a fuel pump next and someone suggested it may have something to do with the torque converter lockup sensor?. if anyone has any helpful knowledge it would be greatly appreciated.
