This just recently started.

I have a 2010 Electra Glide Limited, with the engine warm while at idle at a stop light, my RPMS will kickup by itself. If I try to rev the motor, it seems to choke out, however once moving again, without touching the throttle, i will move forward and everything, the RPMS will stay high for a little but and then it is fine. There are no codes and it only does it when the engine is warm. I have also noticed that parade mode has been turned off.

Anyone have ideas what might be going on?

 

Something simple first, clean your IAC metering orifice at the top of the bore of your throttle body. Use MAP cleaner, spray some on cycle ignition on/off a few times spray again clean residue, go for a ride see if that does the trick.

 

IS the IAC easy to get to?

 

also the top of the throttle body will have a barb for a hose- unused on 49 state bikes- this should have a cap on the top- the caps are sometimes dislodged when cleaning the bike.
make sure it is on or you'll have an intake leak which causes wackiness
on CA bikes this attaches to a hose and the fuel vapour recovery canister

2.) try resetting the throttle sensor calibration:
with run switch on...turn on ignition with right hand- do NOT touch the throttle- wait until the fuel pump stops priming and turn off ignition- wait a moment.
repeat this 3 more times

the calibration can be affected if you use the kill switch to stop the motor- 09's seem to be the worst for this- I no longer use my kill switch

2010 doesn't have an IAC.

 

Could be either an intake leak or the ET sensor going out of range

Both easy fixes.

 

Guys, this is my first Harley. So How can I check for an intake leak? Also where is the ET sensor located? Correct me if I am wrong, but wouldn't a sensor going out of range throw a trouble code? Right now there are NO codes and no engine light.

I just tried the throttle sensor calibration that mkguitar suggested. However if that doesn't work; is there a map sensor that might be dirty? Any other ideas to look at if it continues?

 

to see a diagram of the intake, go here:

select year, then model

then scroll down to the fuel injection assembly...click and you'll see a diagram


#11 is the little cap I referenced above

Get the motor hot and then while it's running spray wd-40 around the intake flanges where they attach to the heads. Any change in engine speed will let you know there is a leak at the flange.

The ET sensor will only throw a code if it is either shorted or open (out of range) but they can drift and make the engine think it's "cold" when it's actually hot and never throw a code.
The way you check those is to either just change it (not expensive) or to put them in boiling water and make sure the resistance over the two terminals changes linearly as the temp rises or falls.

The ET sensor is behind the horn cover screwed into the back of the front head.
