Power loss after replacing the distributor

Hey y'all I replaced my distributor today and it feels like it has lost a lot of power, the cap and rotor and wires arnt even a year old, it has started like hesitating a lot so I am going to replace my ICM soon, any thoughts on the power? Also it is having a hell of a time starting, it had alittle trouble before but now it's everytime

Dude that's bad news. The only thing I can think of is timing but that is set by ecu??? It is on mine but you can put it in far enough out it can't compensate enough. Have you thrown a light on it to see what the ecu is doing with the timing??? Might want to give it a try.

on a 4.2 you still have to set the timing. in another post you talk about having a motorcraft carb and removing emissions, have you disconnected anything? have you done the nutter bypass? without the nutter the computer is trying to adjust the old carb.

I don't have anything different under the hood, how would I set the timing?

sorry, I mistook you for someone else. there should be a tag on your jeep that gives you the timing information. on my 87 it is on the front edge of the hood.
heres a video on setting the timing.

Okay so basically I can do it by rotating my distributor?
