Alright, so I just got this 88 gt off a guy that didnt know too much about cars.. Im not too familiar with ford but Im trying to learn.. I've noticed that when my car warms up to normal temp I get some black smoke out of the pipes.... If Im driving the freeway and drop it to fourth and punch it, I get this rattling noise from the engine and my car spits out tons of balck smoke.. If I dont hear the rattle then the smoke doesnt come.. It doesnt happen all the time, just after she's warmed up and even then not always.. I was told to check my plugs and it could probably use a tune up.. ( new wires, cap, rotor, ect) It doesnt look likes its had one for a while.. Could it be my timing? Please help.... BTW, Ive noticed a strong gas smell from the exhaust but I thought it was becauseI didnt have cats....
