    when i unplug my idle air control valve...my car stalls

    I have some wires that are tapped into my stock si harness...but seriously...theres a obd1 haness that goes from my ecu to those obd0 connectors then branches off to my engine....on the engine side i have that obd1 harness connecting to sensors

    and by the way when i unplug my idle air control valve...my car stalls

    ill have to get a pic of it...its really not at least for everything...mostly everything is ran straight obd1 and everyhting else tapps off the obd0 harness and is jumped to the ecu with the obd1 harness....

    I bought a obd0 to obd 1 jumper harness...and i couldnt use it because everything i have is ran obd1 already

    car runs but when i unplug my idle air control valve car shuts off.....also throws a code when i drive for about 5 mins in 5th gear and left off the gas....

    i just hooked up air fuel controller to looks to be a narrow band o2 sensor from a honda that i installed....

    runs rich
