Just installed 100hp injectors in my 06 cummins. Finally got it to start back up and it idles really rough and i keep getting P0193 high rail pressure codes. Is this just the air working its way out and maybe it will clear up or do I have a bigger problem? Thanks

 

Check to make sure all the fuel connections are good and tight. Any air being sucked into the system will cause rough idle. Might want to also confirm elec connections.
