Hey guys, i have a 1987 lincoln town car with a 5.0. the other day i noticed it was idling weird like up and down, then after that, it started stalling. i would start it go 5 mi with it, it would stall and not start back up for bout an hour, then it would start and stall again. Now it wont start at all it wont fire. we put gas in the intake and still wont fire, there is also a faint spark once in a while. Any help.
