Check the timing, and for vacuum leaks. You can also try scanning the car for codes. You need an OBDi code reader or a paper clip...http://www.muscularmustangs.com/test1.php

Check out the rest of your fuel system. If it sat for a long time and had gas in it the car probably has clogged carb jets or injectors if it is a fuel injected car. A good fuel system cleaning is probably in order to get the car running right.
