Coltonmcdonald5.0

I have a 1994 mustang 5.0 ho 5-speed thats runs great for a bout 30 seconds after i start the thing up! Then after that, it starts bogging out on be quite badly after about 3000rpms. I recently had to replace my clutch and since then my car has been driving very restricted. It seems like maybe my injectors arent giving enough fuel? I don't know..I'm not a mechanic. A little help please?!?!
