alirght iam a new proud owner of a 1986 mustang gt with t tops. I have msd 6a ingintion box and blaster coil. I put new wires in and i still got a miss fire. The other day i had to reseal the valve covers and put in a new throttle body gasket. I started it up and it ran for 3 mins with white smoke coming out then the motor just died. I tryed starting it up but its just cranks and tries to fire but don't get a good fire. Any suggestions would help me out alot.
