Bike starts fine first thing in the morning or after sitting a while. But after bike warms up, It begins to want to die when letting off the throttle. As if the TPS went bad. I've volt tested and it seems to to be good. There are a few times when warm it will idle but if I throttle it and let off, it begins to run bad.
Any ideals on where to go from here?

 

Sounds like a temp sensor or something. Isnt there one on the front cylinder somewhere? Do you have a service manual?

 

First thing is to he k for stored codes. Then resynch the IAC with the ECM. Clean the throttle body, including the two air bleeds at the top of the throat. Then ETS.

 

What did you voltage test and how did you do it?

Hello and welcome.
You have a 96 Ultra Classic ElectraGlide EFI of unknown mileage, unknown modifications and unknown history of ownership.
Your bike is EFI so it has the Magneti Marelli fuel injection system.
We are unable to see it so information helps in order to direct you in a possible direction.
Taking a guess that bike functioned correctly until recently.
In the shortest amount of words it reads like the bike will not hold an idle...like the idle motor is getting stuck.
Does that read correctly?
Is there a possibility that small idle control motor is getting stuck?
That it requires a really good cleaning.
Go to the link below and enter year and then model.
Then go to electrical ignition.
I think the the idle control motor plunger could be getting stuck.
