What does this sound like?
I was coming back from the stables today and noticed some vibration. I figured it was a rock in a tire, so I didn't pay much attention. Then when I got to a redlight, the diesel was vibrating and almost pulsing. The valves were making lots of noise. It was down on power some - not a whole lot, but if I stepped on the accelerator it started vibrating pretty badly.
It ran fine on the way over to the stables (40 miles). I did have to fill it up today and added 8 ounces of a 50:50 mix of Marvel mystery oil and Dieselkleen, but I did that before I headed over to the stables.
BTW it is an 06 PSD CC F350 auto with about 4000 miles.
Anyone have any ideas. I did check the turbo hoses and they are all connected.
If it is nothing obvious, I'm taking it to the mechanic on Monday.

Not only what tvsjr said, but if memory serves, Marvel Mystery Oil is RED. Wouldn't want the dealer making any false assumptions about what type of diesel fuel you've been burning (untaxed, off road fuel is red).

It was indeed the injector on #5. All is well now - however it does take a little more cranking to start now for some reason.
