I recently had my fuel pump & filter replaced & it ran fine for about a week. Now it hesitates to excellerate and seems to miss. It feels like something is holding it back from excellerating. Not to metion I can almost see the gas needle going down. It also feels like it wants to cut off when I'm idleing at a red light.
