Hi All,
    Before getting smogged if you have a digitool attached to your ecu remove it and tuck the ecu  digitool cable in tight and deep
into the cavity behind the wheel well.  If you have an 86 or later remove the tool and tuck the cable behind the ecu  black cover /
holder.
    Yesterday a Sacramento area listee with an 85 couldn't get smogged because of the digitool attached to a digijet ecu.
     First time I have ever heard of this problem.
