Default High idle

I have a 2013 Iron 883. I took the air cleaner off the other day to give it a good spring washing. I had a rag in the throttle body butterfly and was careful not to get anything in there. Now it’s all put back together and I have a high idle. I seem to recall it doing this last time I had the air cleaner off for a changing. Does the computer recognize this & reset after a while?

This may not apply to a Harley but, on my BMW f650gs I have in Spain, the manual recommends if the idle is wrong to switch off, then turn on ignition without starting the engine, then fully open and close the throttle a few times so that the ECU recognises the throttle position at idle.
can’t hurt to try it!

Maybe clean your IAC (idle air controller) If it's sticking you will get high idle. Make sure some cloth fibers haven't caught in the butterfly shaft too.

Check for intake vacuum leak. It can cause high engine idle since it detects lean condition and the computer will try to compensate resulting in abnormal idle....just a thought.

Try this procedure: https://www.hdforums.com/forum/sport...dle-fixed.html

I did not take off my AC, but maybe it's the same problem.
