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.

You don't hear of this problem too much these days, but clogged catalytic converters will cause exactly those symptoms. They are obviously too costly too change on a "maybe" so I guess you would have too narrow it down further. Or, if you're friendly with your neighbors you could drop the exhaust and take it for a spin. `)
