Second Set of Injectors within 40 Days

[gerlbaum]

Ok, so my 2003 6.0 F-350 (~51K of miles) is having injector problems again!! I just had #4 and #8 replace on November 2nd. About 2 days ago it started acting exactly like it was before those two injectors were replaced. First, I found it hard to believe two injectors would go like that, secondly there is no way two more would go just like that without there being some else wrong. Granted I am not sure if it is #s 4 & 8 again but even if it is different injectors there has got to be something else. Anyone have any ideas?

Oh, and I do regular maintenance (even overboard). Just ordered Hot Shot and will be adding it to my oil just in case it does actually work. I use a supplement with the fuel, at every fill up. Finally, no mods completely stock and never puked. Frankly I treat this truck better than my first born and I get no love in return But I do LOVE this thing Like a hot chick with my credit card.

Have you had your FICM tested?

I don't believe I have yet. But would a bad FICM take out injectors?

3 very knowledgeable people told me yes. One very knowledgeable person told me no. So I guess there's a 75% chance that it could.

Fuel pressure/quality.

Hahah, well thanks. Guess the worst case is that I could get a programmed FICM

I thought about that as well. Would the fix be a new pump?

not to hijack your thread but what are the signs of a bad injector??

Now that I think about it, that's where I'd start my troubleshooting. Fuel pressure that is.....

No problem. If basically feels like you are running out of fuel. It will start to idle rough and you will probably start losing power when you try and accelerate. You may not notice anything but a little rougher idle with only one out, but with two down you will definitely notice a really rough idle.
