Newbie here

I have my 2004 F450 6.0 in the shop right now getting diagnostic check done. My question is about 2 codes that I can't find listed on the trouble code list in the Tech folder. Here they are: PO404,PO611.
The diagnostics unveiled MULTIPLE trouble codes including PO275 Cylinder 5 and PO284 Cylinder 8 Contribution/Balance faults. Am I looking at injector failure? The shop is going to replace the FICM and do the reprogramming. Am I going to have to replace injectors as well? For the last 3 years this truck has run very well, except for the last 6-12 months, where it has had some trouble starting,with low power until engine warms up and then runs fine.
Any advice?

 

from what you are describing you might have to. i will try to look up the codes. doesnt sound like a FICM problem to me tho

 

P0611 is a FICM failure code. I wouldn't let any injectors be done until after the FICM is replaced although you might still have bad injectors.

P0404 is an EGR valve code.

Here's a better code list: http://dan.prxy.org/Truck/6L_bible_h...pdate_TOC.html

 

looks like the P0404 is the egr valve and the P0611 is FICM which from what i have read means its cooked beyond repair. so i was wrong the FICM does need replacing

 

Right now, all I'm having done is replacing FICM and having PCM and FICM reprogrammed and see how that works. Believe it or not, there was no CEL during this entire time. Thanks guys.

Those wouldn't throw a CEL on your truck anyway.

 

nope mine never threw a code when my injetors took a crap. not a problem thats what we are here for

 

Thanks for all the info, it is VERY much appreciated.
