Ok, now that I have a day or two off, I am working on the new ride. I've washed the engine bay and such, now I am getting greasy and figuring out why this runs the way it does. I pulled the codes, and for some odd reason, there aren't any. Here is the thing: runs nice when its cold, when it warms up, runs like crap, like there is a misfire. Checked the coils and they seem fine enough to make the car run...checked all the wires, plugs are decent enough, cleaned the TB...what else am I overlooking? BTW, I ordered the new balancer, and the parts guy told me that might have something to do with the running condition as there is a tone wheel for the crankshaft sensor....any thoughts on this?

A what? Tone wheel?
Is he talking about the 3x'* and 18'* pulses?? On the back of the Dampener there are slots that pass the sensor and create these 2 pulses as this a dual effect crank sensor... While you are there you may want to replace the crank sensor as with high milage the sensor can have issues... This could cause a low idle miss... I have a low idle miss thats intermintent on my 91 LE, at this point I am almost positive I need a new crank sensor... But weather or not thats your issues is hard to say...
Cold the engine doesn't miss? Only at hot idle? And if you bring the RPM'* above 1200 do you still have the miss or does it go away?

'm assuming the wires do not say packard on them?
I narrowed it down to a coil pack afterall.....2/5 pack, but as soon as I did, battery konks out....so after this thing is running well enough to go to the parts store I am goin to put it on the analyser....

Sure Willren, here are my findings.....all of the coil packs had tower-to-tower readings w/in the specs you gave in tech info. However, all the coils have less than .5 ohm where they mate to the coil plate, and all vary their readings. I also found alot of moisture down there, so I bet that was culprit too. But their was ALOT of spark bouncing around on all the coil towers when I removed a wire...freaky.
Sand...it may be worthwhile for you to pull the coils and icm back up. I found that my ICM to mounting plate had gotten a light layer of corrosion. Cleaning the plate and bottom of the ICM smoothed out some issues I was having.
