In first gear, start off is very rough if not started off at the right rpm. But in any gear if I try to accelerate to quickly the car bucks, feels like it looses power to the wheels and pushes it back, after about 4 or 5 seconds of doing this it continues just fine. Its NOT the spark plugs/wires or coil thats causing a misfire, because all of those parts are brand new and ford approved. its not a misfire because my CEL off and continues the remain that way.
