Check vacuum lines, near air canisters and air filters etc, usually rubber hoses, may be cracked ,split, dry rot enough to let air in. may as well start there.

1994 Gmc Seirra K1500 5.7 Engine 4x4 hesitation when I takeoff or come to a stop. I have changed the Plugs, Plug Wires, Cap and Rotor and Fuel Filter and still acting up.

What about the fuel pressure, have you monitored the fuel pressure. How about the MAP sensor, have you recorded the siganl when this happens and the O2 sensoras what are they doing when this happens. You have little testing just throwing parts at it from what i can see. Tinme to give a professional a chance here if you ask me.

1993 Gmc Seirra Power Steering

You will have to remove the serpintine belt off take off the Hoses from the steering box be carefull not to strip them out, use some WD-40 or something the make it easier if they wont come off take your time and work them back and forth, If your just doing the pump then take the hoses off the pump not the steering box, take the retaining bold out of the steering pump and it should come right off.
