So, I've searched around and come up with some ideas, but I wanted some more input. My truck had been sitting for a week or two and was hard to start when I took it out the other day (Very unusual, It usually cranks right over even after sitting) Then, when taking off from a red light it started sputtering and almost shut off. Also, sometimes it will hesitate and kinda sputter at low rpms around 35mph when you give it some more throttle. I'm thinking its a fuel issue, but I don't want to start replacing things without diagnosing the issue. Any thoughts on where to start looking?
