2002 wj code p0300 multiple cylinder misfire

Its got the 4.7 v8 125k miles...it started throwing this code occasionally, at high rpm 4k & now more often. Also it seems to happen more severely with the a/c on going uphill, it also throws individual cylinder misfire codes it started with cylinder 4, then 4&7 now 4, 7, 2, 6, it starts great runs good until I get to higher revs.

So I have changed the spark plugs I went with champion double platinum & I have ruled out the coils by replacing cylinder 7 & still get the code for 7

Any Ideas where to go from here?

It is also throws trany code p1793 loss of torque management system
