FICM or Something else
I have done a lot of research for my 2004 F-350 6.0 Diesel. Which I love by the way. I replaced the EGR cooler and while i was in there changed the Oil cooler as well. After I got it all back together and started it. It take a little longer to start, maybe 3-4 seconds instead of within a couple cranks before. Once it starts is idles fine, once in drive it wont accelerate and as i drive it starts to accelerate a little better, but never get over 20mph and about 2000rpm. When i brake it idle rough and then settles once it has idled for a few seconds. There is some, not a lot of black smoke, but some. There wasn't any before. At first I thought it was the FCIM, but decided that i wanted to make sure. after researching I'm at a loss. Any suggestions would be greatly appreciated. The truck has 190,000 miles and is in Scottsdale, Arizona. Warming up isn't a problem at all.
THanks in advance.

If you don't have any thing to monitor or code scan the truck with the first thing you should do is go get the truck code scanned.
If you are having these issues immediately after replacing the oil cooler then it's possible you have air in the HPO system. It's also possible that you got trash on the IPR valve screen. Another thing that comes to mind is the possibility of not getting the FICM plugs back in correctly.
It's hard to know anymore without any kind of diagnostics.

i have double checked the connections, especially since my son was helping me put it back together. I will check them all, especially the FCIM connections when i get home from work.
Thanks for the suggestions. can always hope its something simple

Connected Scanner up to the truck and got no response, Tried multiple times with no communication. Tried Scanner on two other vehicles and worked without a problem. Any suggestions? Bad connection, or bad PCM or whatever you want to call it?

It is typically a blown fuse. Should be the same fuse as one of the power ports (cigar lighter). I don't recall the # off the top of my head but the owners manual tells what it is.

Also check the EP sensor connection and tube for a restriction.
