Type of car, thype of engine

My guess is that you did not gap them correctly or you bought the wrong type of plugs (to cold or to hot)

Black plugs & Gas smell. running way to rich if you only changed your plugs change them back and see if that fixes the problem. If so there is an issue with the new plugs.
