What started as what I thought was a fuel pak problem has turned into a nightmare. My 06 WG started dying when I stopped. Key on and off and it would start and run fine. Cleaned the IAC and that worked for about a week, then it started again. Replaced the IAC and now it starts fine but after a few minutes of running the idle creeps up and the engine light comes on. Local dealer recommended that I replace the eng temp sensor. Did that and no change. I do not have the electrical manual (5-7 days from the dealer) so I'm winging it at the moment. One thing I did determine is that something is telling the IAC to open up all the way and that is where it stays. Even when I key off it does not move thus the high idle, I think. If I unplug and reconnect the IAC it is functions fine. (Opens and closes) Until I start the bike again. So the IAC has 4 wires and is feed by the ECM from what I can tell. What is telling it to open and stay open? Fuel Pak has been removed from the bike so I'm back to stock ECM settings. I have no intake leaks per the propane test. And no codes. Just looking for a little direction until the Elect. manual gets here or I cave and haul it to the dealer.
