I have a 09 Road King and have 40K (25000 miles) on it, stage one air box, with true duels and V&H monster ovals, and a TFI unit. For the first time in 5 years it happened, I had a breakdown. I was just leaving town heading out the highway and switched the cruise on, as I got to my speed I touched the set speed button and the engine light came on at it dropped to idle RPM's. The throttle was useless, not knowing what to do I limped home at idle speed, 10 miles, when I go home I took the air filter off and jiggled the wiring on the throttle body, then started it up and it worked, all was well. I checked the codes and I only had P1511 in history, no others, so I cleared it and drove around close to home all day and it never came back. Now I am worried about going on a long distance trip, we are planning to head south for the long weekend, is there any advice on what to do?
