Fast Idle problem 2012 FXDF 103
i noticed that on my buddies 2012 with a 103, the warm up cycle is LONG and the idol is high... also make sure if you swapped grips that the throttle cables are adjusted correctly

thanks, my 12 FXDWG just started doing it
Thanks for this, I have been looking for answers all night. Sounds just like what I just suddenly experienced. My 103 wide glide started doing last night, idles up from 1600-2100. It is pretty unnerving. I hope it is only a screw. I have a free flow ac, new slip-ons, and xieds. I am taking into the shop today and hopefully they can take a look and it wont cost me much, my warranty ran out a few weeks ago, figures. I have a big ride on Sat.
Normally I would take care of it, but with EFI, I want them to read the ECI and tell me that it is fine and not a bad o2 sensor, or the IAC, etc. Some days I long for my carbed bike back.

Oh sorry man, I was so busy I forgot to share the results.
Yes I took it ot the dealer and it was about a 15 minute fix. There apparently is an idle or Throttle stop screw or something like this which should have been set with loctite but was not and this caused the problem.
With mine the exact idle speed was inconsistant. Sometimes as low as 1500 and on my way over I couldn't get it to drop below 2200. When I went to demonstrate it to the Service Advisor it seemed stuck at 1700.
Generally from the begining of the problem the idle was all over the map but never back down to under 1100 like it should be.
Now it is all good and the was no charge of course.

i had this problem for a bit and then did the ECU recycle that sets the ECU back to factory and it relearns. Never had it again. Also my mechanic took off the one way valve that is in one of the hoses that has something to do with idle. Now that mine is gone idles way better. Much smoother and more consistent.

Idle Screw
Ok, so I'm the guy that responds a couple of YEARS later with the same issue...
So, I own a 2012 Super Glide and I was on a long ride with my buddies. 3 hours into my ride (and far from home) I noticed when I was stopped at a red light that my idle seemed high. Didn't think much of it until I had to stop again at another traffic light. Idle now climbed to 1700. Light changed to green and I put it in first gear with a clunk as a result of the high idle! Next time I stopped the idle had climbed to 2300 RPM's and also noticed the check engine light on. Ok, now it's time to pull over and check it out. Long story short - I told my buddies to continue on without me as I needed to head to a Harley Dealer or home. I Decided to go straight home, turning the engine off at every red light. Thankfully, most of my ride home was highway. By the time I got home, the idle was just below 3000 RPM's. I was hot, tired and frustrated and decided that I will deal with this the next morning when the bike will be cold and It will be a lot easier to poke around for the problem. Yes, I checked the codes and it was a high idle problem. The next morning, I rolled the bike out of my garage and started it up and the idle was at 2800. I shut down the bike immediately. The first thing I did was check the throttle cable. I followed it all the way down to the throttle body (right behind the air cleaner) and noticed that there was a small metal plate attached to the end of the cable that comes down and rests on a small screw. I turned the throttle to lift the plate off of the screw, reached in with my thumb and forefinger and turned this screw back out about 3 revolutions, towards the air cleaner. I was shocked that I was able to grab the threads of the screw with my fingers and actually turn it!!! I started the bike up again and my idle was at 1100 RPM's!!! This is what ruined my ride with friends? A simple 3 revolution turn on this loose screw that would allow the throttle cable to retract more? I was pissed, but happy that it wasn't a big major thing. Ok, so now I take the bike out for a spin (about 2 miles) and everything seemed fine. No high idle and no check engine light. I called my local Harley Dealer and told them what happened. They said to bring the bike in and I did. The dealer is about a 25 minute drive from my home and the bike ran great. I showed the service rep the screw that I turned by hand and I asked him if it would be a good idea to put Loctite on it since it obviously turned by vibration. He told me that I should never under any circumstance, mess with that screw and you can't put Loctite on it in case it needs to be adjusted at some point. He wrote up a service order and took the bike into the shop to have the mechanic check it out. An hour later, it was ready. The service rep told me that they re-set the screw and adjusted the idle where it needs to be. He said that was not the problem. He told me that the bike may have overheated and that is what likely caused the problem. I didn't want to waste my time with this guy any longer and decided NOT to tell him that when I started the bike cold the next morning, the RPM's were very high. He also advised me that if the high idle problem comes back, that I would need to re-flash the bike at a cost of $900. Seriously? There was no charge and I left the Dealer. The next weekend I went out with my buddies for another long ride (6 hours). About two hours into my ride, I noticed my RPM's rising. NO WAY! It took this long for the vibration of the bike to rattle this screw to turn again?!!! I got my buddies to pull over. Sure enough the screw worked its way in (showing a lot more thread and pushing on that small plate causing the throttle cable to be pulled back slightly. I reached in and the screw was very very loose and easy turn back out. My RPM's were now back down to 1050. I told my buddies that I needed an auto parts store or a hardware store to purchase Loctite. We found an auto store, I purchased Loctite (blue), applied a very small amount to the threads, started the bike and adjusted my idle to where it should be. We all waited about 15 minutes for it to set up and dry. I reached back in to try and turn the screw and it wouldn't budge. The remaining 4 hour ride was great and problem solved. Needless to say, I lost all confidence with this Harley Dealer's service department. All credit goes to HYPR for finding this first.
