    JDM 98 B18B into my 98 Civic. I used a 98 CDN Integra ECU. Everything went good except I get this ecu code P1508 Idle Air Control Valve (IACV) Circuit Malfunction. I had my old D16Y8 throttle body on because the MAP and TPS sensors were damaged so I thought that was the problem. I just swapped to a new teg throttle body with a teg MAP and still get the code. I'm going to be swapping the TPS sensor today hopefully. If anyone has seen this or has any insight it would be greatly appreciated.


    Cheers,
    :confused:

    Swapped TPS and another throttle body but still have the code and a really bad idle. Also can't keep pedal at the same position or it starts to hesitate.
    This is driving me crazy please help.
