Having some major idle issues with my GSL-SE again. First off theres this miss. New plugs, new wires, new cap and rotor, im getting new coils soon what else could it be? Also, when i start my car itl sit at about 2200 till it warms up, like its supposed to. Now once it warms up itl drop to 1000. Once i drive it a little thou, when i put it in neutral it will fall to like 5, yes 5 rpm. It gets very low and occasianally stalls. What can i do to fix this>?

Idle air adj, TPS adj. As a last resort fuel adj. All per haynes manual.

set the tps when the car is hot. remove the bac valve and clean it, they like to stick.

you may also have a vacuum leak

BAC valve is what imma try

I cleaned the BAC valve, it now idles at an almost steady 800 rpm, but if im driving along and push in clutch, to either stop, or turn or anyhting my idle will drop down to like 100 rpm for a few seconds then recover to 800. Is there a way to fix that, i think i remember reading about it but cannot find it agian

Sounds like your dash pot is out of adjustment.

I'm too lazy to type since i can't copy and paste a pdf. So hit up this site http://www.wankel.net/~krwright/cars/rx7/85_manual.html and click on 4B Fuel and Emissions 13B, go to page 40 and it shows you if it's properly adjusted and how to readjust it if it's not.
