I have a 2dr manual 2013 JK I seem to have a problem at low speed, letting the clutch out seems like its not getting gas. Stutters really bad for a second and then its fine. Also if your in low speed/low RPM in 4th gear and give it a burst of gas it will stutter for a second. Last night as I was pulling out of a parking lot and crossing traffic it stalled blocking oncoming traffic. It would turn over no problem just not start it sounded like it was out of gas (it had a full tank). After a few minutes it started up ran fine the rest of the way home. No fault codes are showing. My father in law is mechanic he can't find anything wrong with it. However it did stutter with him driving at low RPM he seems to think its something to do with an injector but still no fault codes.
