I have an 06 Electra Glide Classic. It has been having a sputtering problem for a long while. At first the problem wasn't to bad and happened on rare occasions. Last March I broke my leg and the bike sat for a year. Just started to ride again bit over a month ago. Took the bike in for a spring tune up/oil change when I was able to start riding again. Over the past couple weeks the sputtering has gotten really bad and I have taken it in to the shop to have them look at it. They took it out for a test ride (2d time for this problem, first was before my accident with the leg) and they said they couldn't find anything wrong with the bike, and no problem was noticable. The check engine light had come on before I took it in for the tune up, and again when I took it for the problem. 57. P0261 Front Injector Open/Low 58. P0263 Rear Injector Open/Low are the codes that it came up with in order of visits. I just went out and pulled the PO263 code off of it again today when it came on earlier while I had it idling in the garage as I was trying to find sparks to see if it might be an electrical problem. I have looked all over and don't see any. Anyone have a clue as to what this might be? As I was riding to work this morning, my speed dropped 5mph just from a sputter, freaked me out, thought the bike was going to die on me!
