losing power at low rpms

[stillstrokin609]

So i have a 2000 f250 148000. I've recently noticed it seems like I'm losing power while still on the gas to the point where my body wants to jerk. Then power will kick back in and the truck takes off like a raped date. Also while cursing low rpms low speeds its getting more power then I'm giving it gas. Anyone have any ideas what this could be caused by?

start simple and just look at everything, make sure your connections are tight on the valve cover harnesses,check inter cooler boots for cracks holes and clamp tightness,check your fuel filter also look at your turbo for shaft play. I had some problems with mine as my turbo seals began to go..felt like my throttle response was 1/2 unless I really put my foot in it then it picked up. Almost like horrible turbo lag

Look at the ipr valve, sometimes the nut comes off the back side and will cause it to act up like that
