Default Surging at Idle

Allright guys here are the particulars: 96 FLHRI (EFI)with 23k, stock engine and slip on pipes(don't know the brand) Recently, after the bike warms up, perhaps after a 20 min ride the throttle willseem to stick open and the engine will race. When I park the bike and leave it running it will Idle for a whilethen the engine willstart to race. It may startto slowdown and then begin to race again. All this occurs while it is parked. The bike starts fine andidles fine when cold but it starts to surge afterabout 10-20 mins of running time.

Thanks for all the help so far. I've learned so much in such little time thanks to this site.

Pat

Many possibilities, but on that one I believe you may want to watch the temp sensor reading with a scan tool - EVO's had lots of temp sensor failures.
