Starts,idles, won't rev up. No throttle response, only will cough out the intake.Tried injector cleaner, no results.

Had similar problem on 2008 FLHX... I executed the engine codes by using handlebar switches (see your owners manual). The fix was pulling the electric cable connector off the throttle body for a minute or so then reconnecting it. Your bike somehow got into that safety mode of get me home only.
