I just changed my fuel injectors on my 2002 6.6 duramax. Everything went very smooth, when I got it out back together it sounds very rough when running with come clicking. I thought it was error in the fuel lines so I let it run a while and took it for a small drive. It would accelerate. It is reading error codes P0088, P0089, P0090. I have checked the line in the back of the regulator. I have check to see if it is putting more oil into it from maybe a leaking return line. I am now checking for a rolled o-ring On the injectors. Any ideas what else could be going on or suggestions on what to look for?
