probably a bad idle air controller.
It is very likely there is no way to adjust the idle on your car. If your car is idling low, it's probably a problem somewhere else. Idle is likely controlled by the computer.
It probably means that one of your head or tail lights is about to go out. I have a Ford Taurus and my right blinker started blinking very quickly and within a week, my right headlight was out.
the 1989 gt got to 134 mph according to Car and Driver magazine when they tested it.

i don't know if it is a Ford thing, but my dodge did somewhat the same thing... my blinker would flash very fast on the dash and it turned out that my bulbs were out in the rear (maybe that is the problem and your brake lights are connected). When the bulbs burn out the circuit is shorted.
