I am assuming you have built the competition port adapter so that you can run and test auto, etc. Have you checked for bad connections there? Cold solder joints exhibit this kind of intermittant failure. There is also the possibility that some rough handling may have broke one or more of the d connectors on either the RC or OI. This damage is not obvious from the top side. In any event, contact IFI today to get some direction as to operation or failure and replacement.
