Hello I need help I have a 2006 electria glide fuel injected with 43,000 miles. The problem is I will be riding along (over 45 mph) and my engine light comes on if I let off the gas and let the bike idil down the light goes out.I found out I was getting a code and it was rear cylinder no combustion. I changed out my plug wires and plugs and the problem seemed to go away for a little bit but returned. There is spark going to the cylinder when this happens. I have extreme loss of power and my fuel mileage went way down. I need help with this.
I have to say the engine light comes on just after starting bike as well and stays on just a short time then goes out.

 

Check connections to the coil.
