F Me High Idle Woes

Hi all,

I was hoping to get some advice...I have been experiencing on my 2010 FLTRX a high idle after engine warm up, i.e. 1800-2000 RPMs at idle with no return to normal idle. The bike has nearly 17K miles.

I have searched what feels like every corner of the internet for a solution. Based upon other solutions I changed the following: engine temp sensor, crank position sensor, both O2 sensors, checked for air cleaner leaks, cleaned my air cleaner, changed my exhaust gaskets, new battery, prayed to Madonna, you get the idea. Oh yeah I added dielectric grease to the plug that everyone says to do...sorry I don't remember if it was the tca plug but I think so. I have done all of this and still I have a high idle after a warmed up engine. I have checked the codes but that doesn't help, I do not get a check engine light nor does my bike go into limp mode. IDK what to do next other than to go to the dealership and experience what I know to be a $1K non-fix (pessimistic for a reason). Any advice is greatly appreciated.
John

Have you ruled out the the throttle? Like unplug the TBW connector at whatever connector its on under the fairing.

There is an idle relearn procedure but you also may want to check for a vacuum leak. If I'm not mistaken there's a lil rubber boot that can fall off and create a vacuum leak. I believe it's on the throttle body

not the idle relearn, tried it and no love....bike idles fine at startup until fully warm; then the high idle starts.

The 2010's don't have an IAC or am I missing something?

In most high idle situations you can cycle the ignition on/off 5 times and it will reset the idle to factory specs. A ignition cycle consist of turning the ignition on and waiting until the engine light goes off then turn the ignition off, if the engine light doesn't come on after a few on/off cycles wait until the red key light goes off.
The reason the bike idles high is because the ECM will remember the throttle position when the bike is turned off so basically when the engine is turned off when the idle is high then the idle will remain high until you cycle the ignition 5 times. That is why you need to keep the hands off the throttle and make sure the engine idles down before shutting the bike off.
I alway use the main ignition switch to turn the bike off and I use my right hand to do it.
