Did I F' up my injectors?

[mcmmotorsports]

A few weeks back my water in fuel light came on. Called my local dealership, they told me to crack the drain valve and let the water out. It hadn't been 10k miles on the fuel filters, so I figured they were still good. I drained the water out, about 1" in a 20oz bottle. Light came on again a few days later. I ignored it since I had planned on changing the filters out. I finally got around to changing them, they were NASTY. Put new filters in, no longer get the water in fuel light, but now I have an intermittent rough idle, surge at a stop light (SCARY) and just an over all run like crap situation. You could be cruising along, everything ok, then all of sudden, it is like I lifted off of the accelerator when my foot never moved. It has yet to stall on me or give me a trouble starting. I have since added some Diesel Clean, no improvement, and today, removed the fuel filter at the motor and added some Sea Foam up there. It seems better, hard to tell. Filters still look good. I am gonna give it a few days to see if it clears up, but I got a bad feeling some water got into the injectors. Could this be the problem? Is there a fix besides bringing it to the dealer for new ones?

Thanks

sounds like you still have air in the fuel system. are the gaskets on the filters properly? are the caps cracked?

I used new "O" Rings and the caps are not cracked. In fact, it started running like crap before I even pulled the old filters to change them which is why I am leading to believe it is something more serious.

If you havent driven much since the filters change, then the bad fuel you got that had water in it is still in your tank. You run it most of the way out and filled up again yet? Gotta give that stuff a chance to get outa there IMO.

That very well could be it, I may have drove 40-50 miles since the filter change which was 2 weeks ago. I got it down to about 1/4 of a tank yesterday then filled it up. Drove maybe another 20 miles or so since. Maybe I will take a little road trip this morning.

I would if it were me. My bet is once the new fuel gets in there, and you get some miles on her that she will level on off.

According to Ford, it takes 100ml (3oz) of water in the water separator to make the light *come on*. That's not even enough to make it quit. You had no where near that. There is a known issue with the water in fuel lights on these 6.0's. There is a TSB about it somewhere. I think you have a bigger issue that just happened to be at the same time as the water in fuel light.

Dirty filters is not good. That puts a horrible strain on your fuel pump. I think more likely than water in your injectors is damaged fuel pump.

I am not a expert but it sounds like an EGR problem to me.....

You got it right on the money. Ran about 400 miles yesterday and she runs beautiful again.
