Check the resistance of the plug wire end caps that connect to the plugs, if it is too high they can cause miss fires. they may indicate firing but not getting all the voltage. also check for a fuel problem, ex: not enough fuel entering the cylinders. another thing to check is cylinder compression and valve adjustment.
I will definitely have to check the resistance in the plug wire end caps. Just after I changed all my plugs I went ahead and recleaned my carbs because that is what that to happen.

you wont have a distributor cap m8 as you have a coil pack which you have already changed i would start looking towards your injectors!

If it is only doing this in overdrive lock up, tap the brake if it quits see a transmission man your torque converter might be bad

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.

i have a 2000 jeep cherokee and random cylinders are misfireing so i changed the spark plugs and now its just reading that cylinders 4 and 5 are misfireing. it drives fine around town but if i go 70 or a little over on the highway it starts to buck or bogg out i dont want to spend the money on a coil pack without testing it first but i cant find the specs to test it idk what to do????
