I have a 98 e150 with a 4.2 V6 and it is sputtering under acceleration, kind of like its getting choked out or running out of gas and usually backfires during this. I have replaced the plugs, wires and fuel filter within the past 4 months. When I do a full throttle acceleration the problem is not as bad but still exists. I replaced the coil pack when this started with no improvement what so ever. Any help would be greatly appreciated.
