First, Check your EGR Valve. It's easy to get to and pull, and easy to clean. Takes 10 minutes to pull, clean (use a good solvent and a toothbrush.), and reinstall. If it sticks open during normal operation, even a little, it will divert exhaust from your turbo into your intake, causing lack of boost, and horrible performance. If that fixes it, replace the valve, or, just delete the EGR! =D

If you do that, and it doesn't change, you might need to pull the turbo and clean it, as the VGT Valves in the turbo might be sticking. Not too hard to do, you can do it yourself if you can operate basic hand tools.

Thank you very much for the advice. I have an Egr delete kit that I bought a couple of months ago just havent had the time to install it . Now I guess that will be the next thing I do.

So I cleaned the egr valve and now the truck runs great but I am still getting a code that the egr is insufficient flow. and when I turn on the heater I think I smell exhaust but It might just be me head playing tricks on me.

The flow code could be stuck from prior to cleaning your valve. Clear it and see if it comes back.

After cleaning the valve, if it's fried and doesn't open when the PCM tells it to, it could cause that code.

A EGR Flow code is annoying, but AFAIK, does not affect operation at all. Everyone with an EGR Delete in a later model year will get that code, and most of us just use a tuner to perma-defeat the code.

I have a Triple Dog GT, I cleared it and it just came back. So this weekend I'm goingto install the delete kit so I can be finished with this EGR problem. Once again thanks for the advice.
