    I just bought a 2007 Road King with 20,000 miles on it. Before I bought it I rode it a couple times for 30 min. tops both times, no problems. First time after purchase I rode for a little over an hour and the engine light came on, when I slowed down to check it over the idle rpm was up about 2000rpm's. I was close to home so I headed back, by the time I got home it was also running rough anytime I rolled of the throttle. This is my first Harley, no owners manual (its on order). Bike previous to this was a Suzuki 1500 Intruder, so I'm out of my element. Anyone give me a clue where to start?

    Thank you, this helped a lot. It showed a DTC - P0505 Loss of idle speed control EFI & P0152 Rear O2 sensor high (rich). Now at least I know where to start. Once again thanks for the info.
