I'm almost wondering, if your dealing with a wiring sag kinda problem, where something is intermittantly touching something hot or grounded that it shoudn't be. I'd suggest try letting it idle, and move/twist on every bit of wiring you see, and see if it stumbles. pull every sensor pigtail apart and reconnect them. Pull the main harness connectors apart and check for moisture or corrosion. Spray some WD-40 into each one as you go.
I've solved a lot of phantom problems doing this.
It has been said that up to 90% of all performance issues on feedback controlled cars stem from bad connections and grounds.

Well, i finally got all the stumble, cough, spit, backfire, high idle stuff fixed. All it took was a new crank pos. sensor and a new Ign. control mod. In all my searching online and books i have not once saw anyone say that a ICM had anything to do with idle air control, but apparently it does. Crank sensor had cracks around it, looked like plastic fatigue from heat/cold/age. Im not sure if it was "totally" bad or not, but it was cheap enough to replace. ICm on other hand was 80.00
Running fine now, smoother than it ever was. Oh, by the way, its 91 2.5 TBI engine with DIS Ign.
I also used heat transfer compound between the IDM and its alumium heatsink, none provided with new ICM though, cheap A***
thanks for the replies, yours and the other hundered's of posts i have read about stuff like this helped make the decision to buy those parts.
