dtc code p281,after egr removal..

I just replaced my oil cooler and did and egr delete,now I am getting this dtc - P281 - Cylinder 7 Contribution/Balance. Is this an expected code for egr delete ? I didnt have it before,but sort of figured I would get some dtc once removing the egr cooler. Any ideas..... thanks,Robert

The expected code for an egr cooler delete is the infamous P0401 code (insufficient EGR flow detected).
Contribution codes usually mean bad injectors. Since you had the injector harness off the truck, unplug #7 at the head check the pins and plug it back in, then get the clip on. I had a bunch of odd codes from not getting the FICM plugs all the way in when I finished...

PS: Cylinder #7 is the one closest to the firewall on the passenger side.

Ok I'll check that out .The truck started right up and idled fine,I have not driven it yet.I sure hope thats the problem, of course the way things go for me it might be a bad injector.

Happy that that thread is helping others, but it is actually a collection of everybody's hints, tips and suggestions from a few forums. I just remembered what they were and wrote them all down for everyone to see in one place, along with the files I happened upon while trolling the net.
If you have anything you want to add to that post, let me know.
