ok so i just had a BDL 70MM Throttle body on my Z3 swap and besides the idle would act up from time to time it also got stuck at times. i decided to switch it out for an OEM k20A-TypeS throttle body with an oem TPS sensor that remained untouched; after installing i noticed my RPMS higher than usual, i drove it around and noticed that my throttle wasnt opening up entirely and then my idle went up from 1300 to 2k rpm. i tried to trouble shoot it but no luck at ALL. now i need help from the experts on here, is there any other mods to support this throttle body needed on my Z3 swap? i have the adapter on it and gasket but the idle is WAY too high and i cannot get it to go down, do i need the throttle bracket Karcepts sells as well as NEW rsx throttle cable? PLEEASEE help me get rid of this!
