I have a 09 roadking and it seams that while out riding at times the CEL comes on and it goes to idle. when you throttle it up it doesn't sounds like it's only hitting on one cylinder. i can shut it off then unplug the spark plug wires and hook them back up i can take off again. I have noticed that when i leave from a stop at full throttle it really does it a lot sooner but if i'm out riding it only happens at times.
any advice on what to check would be nice.
