If you put a Ford Focus oxygen sensor on a 2003 mustang gt will it cause the engine to stumble at idle speed about 55mph? It has been doin that to me and a mechanic put the ford focus oxygen sensor on there and i have already changed the plugs and fuel filter. Would the focus oxygen sensor cause it to stumbe?
