My 2008 1800 idle is not steady. It has started to go up and down. Does anyone have any idea why this would happen. I have 23,000 miles on it.
Man, I am glad to have read this and discovered the ECM reset; THANKS for posting that!I think I would try to reset the ECM. Here is how to do it.........
Your ECM more than likely just needs to be reset. Here is a very simple procedure for doing that. Note that you cannot use the throttle at all during this process or it will not reset the ECM. With a cold engine, start the bike and let it run until it reaches normal operating temperature. Listen for the cooling fans to kick on. Let them cycle through one cooling phase and when the fans shut off, turn the bike off. The next time you start the bike, it should be running more smoothly.
Hope this is your problem and this helps !!
