I had the exact same problem with my 94 T-Bird, except it was cylinder 8. After changing everything you mentioned "plus the fuel rail and injectors" I thought I would try one more thing..." THE COMPUTER". Believe it or not I replaced it and the problem was finally solved. The computer was going out, therefore causing the #8 injector to constantly pour fuel into the cylinder. Sparkplugs couldn't ingite all the fuel. The only other place the fuel could go was out the exhaust. Hopes this helps.
