I was having issues with a misfire after long periods of idling, but once on the highway or after the car sitting and cooling off it ran smoothly again. The XR700 ignition had just enough wire length to put the module in the interior on the other side of the firewall to get away from under hood heat. This solved all the issues. However, the wires were stretched tight and the XR700 unit was just sitting on the glove box tray. I used the same gauge wire to the coil and ground and the 3 distributor wires in order to extend it about a foot in length so that I could mount it properly and route the wire nearly through the engine bay. Everything secured with heat-shrink connectors but no luck starting. Red light flashes on the module, but not firing. Would lengthening the wires affect the system?
