I have a 2010 FLHTK, configured as described in my signature below. I'm having a problem lately with my idle when the bike has been sitting at idle for a while after the engine is already warm (i.e. long red light). The RPMs start dropping, then it sounds like it is firing on one cylinder until the RPMs drop too low (<900) and it stalls. I have to keep goosing the throttle to keep it from stalling. The EITMS is disabled, but it seems like it is firing on one cylinder at long stops anyway. The RPMs are normal at idle unless the engine is pretty hot. I had it serviced at 25K. There is 28K on the clock now. New spark plugs at 25K. It runs great otherwise. No DTC codes. I'm using one of Fuel Moto's maps for the Pro Vision Tuner. Any ideas?

 

Check the air filter.

 

Clean your IAC Sensor

 

I'd say call F/M as that is more in their venue, wouldn't you, or have you?

 

Guys - Thanks for the advice. I checked my air cleaner and it was pretty bad. I thought cleaning it was part of the service I have done every 5K. Lucky for me the filter hasn't been on the bike all that long. I cleaned it up and it idles a little better, but still ends up doing the same thing when hot. I'll give Jamie a call at Fuel-Moto and see if he has any ideas. I'll also look into the sensor one of you mentioned.
