Fast idle problem

[flamerod]

I think I might have a bad temp sensor. The first time I start up my Road King it runs at 1800 RPM for 4 to 7 minutes. It doesnt matter what the weather is warm or cold. It can't take 7 minutes for the bike to warm up when it's 80*. The local Harley dealer is just about worthless so I can't ask them. I had one independent shop tell me it might be an air leak. But when it comes off fast idle it idles at 1000 RPM and runs great. Any Suggestions?

My fatboy did this very thing last year.. I tryed to cleaning the idle air control. that would solve the problem for about 600 more miles then idle very fast again. finally replaced it with a new one and has idled correctly now for 2000 plus miles.
hope this helps.

I had a chance to check things out today. I uplugged the TPS and reconnected it a few times. I checked cables, looked for anything sticking or hanging up (found nothing). I started the bike and WOW 1500 RPM not 1800. In two minutes it was running at 1000 RPM. It has never done that in the month that I have had it. Must have been the connection on the TPS. We will see what happens tomorrow morning......

Not sure if you fixed your problem, or what year your bike is. If it has TBW then make sure you let the engine idle all the way down before you shut it off. Mine was having a similar problem. Pulling into my garage i would throttle to get in and just shut it off and coast the last couple feet. The CPU will sometimes revert the idle to the last rpm the bike was shut off at. My local indy told me this and ever since I jsut make sure the bike rpms down to idle before shutting off and have never again had a high idle issue.
