I just swapped a b16a1 into my 91 civic si and everything seems to be working fine except when the engine gets to operating temp. the idle starts jumping from about 1300 rpm - 700 rpm when it idles. Does anyone know what to do to fix this? I have been told that I might need to adjust my idle adj. screw on the throttle body, but Im not sure. Please help!!
thanks!
