No idea how to diagnose, Was told it's the coil pack, but not sure what that covers other than the ignition coil, distributor cap, and rotor. Was reassured by a mechanic friend that it's not the TPS, and the Fuel Filter is Brand New.

change all, plugs cap rotor and wires you should be good after that, coil packs are 00 and 01 cherokee and your kinda lucky there its a coil rail and its $130 or more for it.

The coil pack can cause a misfire. So can a bad rotor. I'd say change the coil and see what happens. Then if nothing change your cap and rotor. If it's still misfirong move to your plugs and se if they are fowled out. If so replace them and make sure they are gapped right or it won't do you one bit of good.

Also check over some things. Make sure your timing is set right, track down every inch of your plug wires and make sure they are not rubbed through anywhere.
