ok first off i know alot of you are thinking well why'd u use a OBDII engine in a OBDI car .. well it was free i owned a 00 SI and totaled the rear and scored a 93 cx for 400$ with blown engine from some hippies .. lol .. ive converted the rear and front disc brakes with proportional valve.. easy task ... i ordered new axles for 00 si also used my si shift linkage and bought a new rear tranny/engine mount from honda .. everything is in the car already .. heres where it got complicated .. well first of all i had the cash so instead of trying to fuss with the wiring i had both harnesses sent to Hasport and they became one i installed the wiring harness after my 3 week wait in bout 20 min ... including the four wires i was to relocate on the ecu harnesses .. and yes i have a OBDI civic si ecu .. well car started but idle was jacked .. ive played with it for a good day trying to get idle to correct itself .. so far ive tried 3 different Iac Valves ... i was getting 2 cel codes a 14 which is Iac Valve... and a 41 which was primary sensor heater .. i corrected the 41 code .. so heres the thing .. on my Si behind the IM there is a vacuum... where in the hell does this thing go ??? ive hooked it up to the purge valve from the cx engine and so far the car idles normal ... but when u try to drive it ..... the fuel cuts on and off ... or chokes or something .. above 3000 rpms the car roars and gots all the power id imagined it would have .. but the whole throttle body dance up my entrance and in traffic is quiet annoying .. ive searched and searched and ive only gotten some half a$$ diagrams of the vacuum lines .. so im asking for help here who can help get this problem corrected ?? im gonna try a new throttle body gasket in the A.M. but i have a feeling its a sensor plug thats crossed or a vacuum i forgot .. any help is greatly appreciated .. thanks
