If you plan to remove the lower intake manifold, you probably have to remove pwr steering pump indeed. Otherwise it makes a difficult removal/installation.

You did not mention if it was the intake to the cylinder head bolts (1993 buick lesabre 96 in-lbs)..... or ..... the intake upper to lower bolts ( 1993 buick 132 in -lbs) but i hope you will know wich you are looking at since there is a large difference in torqe.
Tightening the bolts in the typical order from the middle out, the upper intake bolts torque in first pass at 44 in lbs, the second pass at 88 in lbs. The lower intake bolts start with 27 in lbsfor the first pass, 106 in lbs for the second pass and 133 in lbs for the last pass.

upper or lower? either way, remove all wiring, 8 10mm bolts that hold upper intake, both fuel lines in right rear(inlet, outlet) remove upper intake. 8 13mm bolts hold lower intake. dont need to remove lower intake if u r replacing injector assemble which is probably what u r doing as this is a very common problem with the vortex engine. be sure to replace as assembly and not just regulator if the vehicle has 100k plus
The '99 has more bolts. If you have the lower intake also, you can swap the whole thing. The upper alone wont fit. Intake issues are very common for these cars.
