You also gapped the plugs to the .065 right.  You will like it. 

Does gapping the plugs at .065 help with it running rich?  What is the benifit?

With the modified screemin demon coil you can run them at the higher gap.  The standard coil does not have the ump to push the spark. The wider gap gives a larger spark and a more efficient burn of the gas dumped in.  Suppose to mean less raw gas just passing through to the exhaust and more effective use of the gas sent in.

so how do i test a CPS???

You'll need a multimeter I believe.  Although you can quickly test it by disconnecting it and seeing if the engine even starts.

how are you guys checking the codes? do all of you guys have a code reader? if not will you let me no how to read them or check them.mines kinda doing the same thing.no local mechanic shops around here has a code reader for my 92 i dont want to take it to the dealer thell charge a fortune.mine will do it mainly in third gear and up if you hold the throtlle steady say at 3500 rpms it will hick up or even seem like you are turning on and off the gas to the motor as quick as you can.   

exactly !!!!! mine is doing that !!!! HELP ? What did you do the fix it ?

we are still working on the problem, when we finally figure out the solution it will be shared with the world

i just changed the o2 sensor. Seems to make a world of difference.

my o2 is new doesnt do shit

Okay my hicup is fixed! I believe it was a combination of 2 things but, I think it all started with the spark plugs. I had installed those Bosch Platinum +2 plugs a few weeks ago which is about when it started. After doing a bunch of Web research it seems a lot of Jeepers have tried fancy plugs like these and found their Jeeps run crappy. Putting in the hotter screamin deamon coil cured the problem which may have been created by using those fancy new plugs which by the way cannot be gapped because the ground electrodes are on the sides. So after some research on the Web the Jeep spark plugs most recommended seem to be the Champion Performance Truck Plug # 4412 which are the normal design you can gap. It is my belief now that the multiple electrode Bosch plugs require more power which creates more demand from the stock coil and it starts cutting out under load.

i hav champion plugs now  lol.  plus its cold out so no sputter, maybe i just  gootta move to anartica?

[Tall Boy]

I think Champions are made specifically for Chrysler/Jeep products. Auto Lite is Ford, Bosch is Chevy ?, and Nippenddenso is Nissan, and NGK is Toyota and I don't know the rest for Hyundai and KIA, and Daewoo, and etc...

ok so apparently rain effects my jeeps performance, it hic ups more it the rain and stuters annd stuff. 

[kenny kustom]

mine it still doing the same thing .... I am moving on to electrical, as it happens more when going over bumps.

Sounds like water or moisture in your ignition system someplace.

[Guardian7]

That usually indicates the distributor cap or wires are getting wet and need replacing if rain causes it to spudder more which I have seen happen when steam rising off the hot exhaust gets into the dist cap or wires begin to arc to near by objects when wet but you cant rule out wiring either. Arcing wires can usually be seen when it's dark, try getting it wet at night then watching for arcs from the wires, cap, and coil areas in the dark.

PROBLEM SOLVED. cheap auto zone parts suck, the rotor didnt fit snuggly on the distributor, whihc caused the timimg to be off, and me to spend like 250 in usless parts grrr but yay its fixed.

  .. good another jeep running good is an infinite number off good times added to the possibility's
