    i have a d15b7 i swap into my rex i found out tht a h22a1 has a big bored throttle body i think its a 64mm and the b7 has a 54 to 56mm ;) the only problem im having is tht my car idles at 1500 rpms :( but when i get on it it hauls :D idling at 1500 rpms burns more gas and is annoying .....what should i do ?? i dont have the d15b7 throttle body anymore



    it has new gasket
    new hoses
    has been cleaned
    and the screw under the throttle where the cable hooks up is completely down is there any other way to adjust it ??

    check for any loose/cracked vacuum hoses..also check the iacv and fitv..and check to see if you tightened it down
