I have an 01' road king classic fuel injected. I have it set up with V&H true duels and PC. I just picked up the bike this past January. The previous owner had told me that every once in awhile it registers a code from a mis-start. Also, sometimes the bike shakes after at idle after he went to the true duels. Anyway, I've been riding the bike with no issues so far. I have experienced the shaking but it doesn't do it all the time. The other day I decided to take it on a good long ride. I noticed that it was registering a historic code but I figured it was from the starting issue. About 45min into the ride, the check engine light would come on and stay on for about 30 seconds or so and then go off. The longer I rode that day, the more frequent it would do it. So I figured I'd clear all the codes and try to get the engine light to come back on and check that code. I unplugged the main harness for about 30 seconds and that cleared the codes. I rode it for another 2 hr's and the bike ran perfect and the check engine light never came back on. I even noticed that it was idling much lower and barely shook at all during idle. Any ideas??? I really appreciate any feedback you could give me on this issue. Thanks!
