Rough idle, loss of power and heavy vibration when accelerating?

[TxRanger3006]

I have a 99 f350 7.3 that was driving fine all day, when I stopped to fuel up all of a sudden I had no power it idled rough with a real deep low tone and when I would accelerate the whole truck would vibrate violently. I was able to limp home but now I'm stuck I can't see any diff on the suspension or engine? I also didn't hear my turbo and couldn't get above 40 and once I got to my driveway it almost died goin up it????? Any help would be great...

Same thing just happened to me, half hour from home, not sure if I want to chance it or not

Mine ended up going away but when I get on it pretty good it will come back then go away again, not quit sure what the deal is though

I got her about home now and then i'm going to do some searching, but it is getting worse and worse right now

What could be happening is that the engine has dropped cylinders because of the electrical connections under the valvecover (UVCH) are poor. It's not uncommon, and the first thing I would check...

i'll check that, but my main concern is that it isn't even throwing a code at all

You have the right equipment to read our codes? You know a Generic OBD-II reader is of little use for this engine...

To diagnose a UVCH issue you need something that will read IDM codes, perform a Buzz Test, and then retrieve the results from the IDM again.

No i don't have the right equipment I just mean that my SES light hasn't even come on

probably either a UVCH or a fuel delivery issue. Did it start right when you fueled up? If so you may have an obstruction

[rjm0027]

Yeah it started right up as normal, going to pull of the valve covers and have a look today
