I have a 78 spider with spica and cannot get the sob to idle at all. I looked at the wiring diagrams and see that there is a ignition relay that is connected to the de-cel sol and micro switch. That relay and wiring is missing. Car will run alright but as soon as I take my foot off the gas the car will die. Any suggestions. Would the de-cel not being hooked create the lack of idle? Any suggestions will be appreciated!!
