engine light was on I installed new camshaft position sensor, upper intake on 2002 Ford Windstar

gasket set, new wires and plugs, and erg my light has stayed off great except when I get around 30-40 mph it still feels like its missing but when I give it gas it runs smooth and and stopps missing could it be fuel problem? Transmission is smooth and shift into all gears properly but in town around 30-40 miles it feels like missing
