I have a 1995 mustang convertable with a 3.8 V6, it is idling over 2000, I have searched for vacuum leaks, I tried a new idle air control and that made it go up to about 3000, I dont know what to do next......does anyone have any ideas?

 

clean the throttle body
and there should be and idle ajustment screw like on a carb on the tb see if that will adjust it down
