i think i know what is making it idle low. there is no coolant running through my trottle body. so the cold idle adjuster doesnt work. its just adjusted so it is always off. is there any way i can make my car idle high for a cold start but then drop off to around 750RPMs. here is a little write up on how to reomve the coolant running through you trottle body. http://www.rx7.org/Robinette/throttle_body_coolant.htm

Ugh..Im sorry if this is splotchy information...but my FD is a few hundred miles away from me at the moment and my memory is terrible, I had a slightly similar issue..but if you can find your way into the Idle adjustment screen of your PFC, you can change the idle based on ECT...I think its 10 degree centigrade increments...and the idle can be adjusted 100 RPM at a time..Hope that helps!

in the idle adjustment you can only change what the idle is based on if there is an electical load. (as far as i know anyway)

Yes. Return the throttlebody cold start system to stock configuration. It's there for a reason. I don't get how people remove factory equipment and then wonder why they've lost it's functionality...
