ok the car will at 750 but i cant get it to stay at 750. when i let off the gas the car idles at 1200-1500 but if i slow the and hold the clutch out til about 800-900 it will idle at 800-900 depending on where i release the gas. any had this problem or know how to fix it? any thoughts on this topic would be helpful.

youll want to clean the air bypass, i think 1300cc.com describes this.
check the TPS setting, check for a sticky dashpot, clean the throttle body itself.
and if all else fails do what i did and adjust the throttle position set screw or whatever its called, i dont think its meant to be adjusted but my car was wildly loud idling at 1500.
edit: honestly id just take the dashpot out all together to prevent misdiagnosing a broken one as working properly, i took mine out and nothing bad happened.

grab the factory service manual (fsm) from fc3s.org or teamfc3s.org.
the dashpot is this little round thing with a plunger out the bottom that is by the throttle body and acts as a damper by slowing down the release of the throttle.
youll see it if you get the FSM, look in the parts index for dashpot then go to that page.
