When you say that the car has a rough idle do you mean that the rpm's jump from about 500-1300 rpm because if it does i had the same problem and all it was was just a dirty throttle body and i used some carb cleaner to clean it out. This problem started when i unhooked the battery to fix the headlight switch, so unhooking the battery could've been the start of the problem if you did that.
