Stalling problem

I have a manual 1999 F250 with a 7.3 liter V8 im in love with... however, ive been having this problem. It will start fine with the most part and idle normal, but when i get about a block down the street, it will start to make loud noises and try to stall out... i have to put it in neutral and sit on the side of the road until it stops idleing rough and can run again. Then as im driving it will run fine until about 65-70 mph where it kicks out a cloud of grey smoke (not the normal turbo black), and sometimes completely stall out as im driving, then take a moment to turn back over.

I am assuming its a fuel problem as I have changed out the timing sensor in the front which helped a little, and checked the fuel filter on the top of the engine and that checks out fine, as does the fuel pump... is there another fuel filter, or does anyone know how to fix this?

Thanks!

When the engine is running rough, do you get a Service Engine Light ? What part of Florida do you live.. maybe someone can drop by and read your fault codes..

I would say maybe it is the famous under the valve cover piece of junk of a plastic connector (UVCH) harness is coming loose.. a very common problem. It maybe just one side.. but you should check both sides.. the valve cover gaskets are reuseable..so there is no cost, all labor...
Here is a link to show you how to fix it.. (but it would be nice to read your fault codes to confirm this, a P1316 is the usual code)...

Sounds like the screens in the mixing chamber are clogged. The "loud noises just prior to stalling out" symptom points to a fuel flow restriction. Sounds like there is enough fuel flow at idle and light throttle driving but not during acceleration or highway speeds.

If you have a fuel pressure gauge that you can hook up and watch while driving then you can verify the potential flow issue. Even if the in tank pickup is clogged, you might still get good fuel pressure at idle so it's something that really needs to be monitored while driving.

Here is a link with a remedy to clogged pickup screens.

Times 2 on what Greg said. I have been through this same issue with my truck, I replaced the fuel pump, the IPR, and after all of that got to drop the tank and clean the screens in the mixing chambers, I did not do the hutch and harpoon mods then, though i am not sure if and when I will unless i have to drop the tank again. I had to do mine at 185k miles and the screens were black as tar when we pulled them out. I had a spare set of screens that a friend swapped with me and he just cleaned my old ones later.
