[fire95birdlt1]

hi guys i have firebird formula 1995 LT1
when i start my car it look like its running rich.The carbon on the pipes, the rich smell, and the burning of the eyes tells me (maybe wrong) that I am running rich .can any one tell me what it could be?well i recently bought the car and i checked the spark plugs its platnum NGK TR55gp and i checked the gaps they all were up and down so i set all the gaps at .055 is that ok and all the plugs were black on the tip look like carbon.i have seen most of the people they put NGK TR55s so like to know what is the diffrence between this and in my car?should i change the spark plugs into TR55s?will it solve the problem?
