Icon4 4.0 Sensors VS 3.0 Sensors.

Guys I have been having the same problem with my truck now for a while and no one can tell me what it is. I thought it was the fuel pump at firtst but it does it so intermitantly. When I am going along the truck will buck and chug and the more I try to press on the gas the more dead pedal/ the motor cuts out. I could drive it for a couple days and not have it do it, other times it will do it all of the time. Weather is not a variable it does it in all conditions. It has new Autolit Plugs and Wires.

My question is will any of the followign sensors of of a 94 3.0L work on my 94 4.0L?
MAF(Mass Air Flow)
TPS (Throttle Position Sensor)
Crank Shaft Position Sensor
EGR Valve

If so which one should i try first? If not does anybody have an idea of what the issue could be?
THis is my only transportaion and I have been getting rides from co-workers. Cash is tight and its possible to spend thousands and never find the problem. I put it on a code reader and it told me TPS and O2 sensor (left bank). My MAF I swapped with my brothers truck and it didnt do any good to mine or bad to his.

Any insight is appriciated.
