97 Road King with Morelli fuel injection. When it is completely cold, I have to crack the throttle slightly to start it. After it starts, it idles up and down for about a minute. As this is happening the check engine light will come on then go off several times. I tried to get codes out of the bike using both the ignition switch method and by shorting terminals 1 & 2 together at the connector and retrieve no codes. After the bike runs for a minute or so the idle returns to normal and runs fine. It has to be stone cold for it to act up. Any ideas would be appreciated.
