So, I have an 88 Range Rover, 3.5.

It starts after a few cranks, idles (a little bumpy), and when I depress the accelerator, it spools up to 1200-1500 and then bogs out. To bring it back to idle, I need to feather the throttle until it is back.

I have done the following:
coolant sensor
idle air by-pass motor
fuel filter
fuel pump

With all of that, the exact same thing occurs. I have researched the same symptoms, and everybody seems to fix it with the fuel pump...that was my last effort.

Can somebody please guide me. What should I do from here.

Have you checked for air leaks, allowing unmetered air into the engine? Easiest way to check is to spray some wd40 or similar around areas that air could leak into - if the revs rise (due to the wd40 burning in the cylinder) then you can track the leak down. Obviously the downside of this is the whole spraying a combustible oil around the engine thing, but you can do the same thing with water spray, and listen for changes to the revs.
