I have a 2013 commander 800, right now it idles weird. Has a small sputter like it can't figure out how much fuel it needs. It will idle fine then sputter. Doesn't matter if it's warmed up or on a cold start. Does the same thing while riding especially when you are trying to just putt around. If you mash the throttle sometimes it sputters then picks up runs fine, other times it doesn't do it at all. I went for a short ride with no problems then started it up today and it had this issue...any ideas?
