Try tightening the intake manifold bolts to get rid of the intake leak. If that does not work then it has to be pulled like you say. The EGR Valve can make it run rough also if it is stuck open and not working properly. Should try and clean it along with the port it sits over. You should check the fuel pressure also, it should be 9 to 13 lbs. Possible the fuel regulator in the TBI may need replacing.
