Stalling out on 1994 Chevrolet 1500 Pickup

i tried replacing the fuel pressure regulator,spark plugs, wires and idle control valve. The truck still cuts out when you press the gas or if it doesnt cut off fully it acts like its bogging down and about to cut out.

Check your plugs, are they really rich? Check your serial data from your computer, it will tell you if you are running too rich or too lean. Check your coil out put, it needs to be at least 80k which means it can jump about 3/4 of an inch and will REALLY snap. Take the coil wire off the main coil terminal and have some one crank your motor. The coil should really snap like a snake. What kind a shape is your cap and rotor? How long since your replaced your fuel filter? Hope that this helps.
