I installed a IAC adapter from Full Throttle and I can't get the engine to start up or idle while cold without opening the throttle some. While holding the throttle open enough to keep the motor barely idling the Iac counts are at 175. I have a new IAC motor. I tried opening up the throttle blade and re adjusted the tps and then once the motor is up to temp it idles to high and the iac counts are at 0. What did I do wrong installing this thing?
