I have a problem with my 01 Screaming Eagle Road Glide. Both after just starting and after warming up, the idle drops down below normal and eventually the engine dies out after about 10-20 seconds. I was thinking it might be a leak in the intake, but I sprayed WD-40 and carb cleaner around the intake and didn't see any change in RPM. My guess now is the TPS or the ISC. The bike has around 22k on it. Any thoughts?
