just recently got JDM type r motor swapped into my 94 integra. Car runs nice but has a strange idle problem. At a stand still the car idles fine. But once i get moving the car runs good until i let off the gas, the car starts to rev and then it stays idle at 3000 rpm. it doesn't get back to normal until i come to a complete stop. Once i start moving again the same cycle starts over again. Does anyone know why its doing this? At a stand still the car idles perfect. Any help would be appreciated.
