idle problem

B16 swap done recently, replaced cap/rotor with 90 integra cap/rotor. Replaced wires w/ Magnacore 8.5 racing wires. Cold Air intake also installed. Have a very low idle around 500. Tried screw on throttle body and it would only turn 1 revoultion counter clockwise (after screwing it in all the way). Was wondering how to get screw to loosen more to adjust idle?? There is plenty of anti-freeze in car. Havent yet looked at PCV. Could you help…
