P0264 Injector Circuit Low - Cylinder 2

Just had an EGR Cooler delete installed on my '06 F-250 PSD. When I got the truck back, it was showing the code P0264. I cleared the code but, it came back. The truck is idling a little rough and is really rough at about 50-55 mph...just about where it shifts into high gear. The techs had to unplug the fuel relay at the same time due to also installing an alarm system which required the ignition to be "cycled". I've talked to the tech and he is telling me that this is a normal occurence when air has gotten in the lines. They did prime the injector lines after they finished the installation. Is there something else I should be looking for? He says that it should clear up once the truck has been driven for a while and has gone thru the "drive cycle". Thanks!

What ever came of this? I'm showing the same code. I don't think my airdog is doing its job of taking the air out of the fuel

I too have the same code and symptoms. I fueled up a while back and got a tank full of water from a gas station. drained the tank and installed all new injectors (stage 1) and now get this code with the rough idle when the truck warms up and a wicked hitch in the giddy up after shifting into overdrive.
Are we still thinking it is air in the fuel?
