EGR Valve
Well I replaced my EGR Valve in my 2006 6.0 Turbo Diesel and I'm still getting the code feo EGR Flow insufficient. What could be the cause of that? One guy at the Auto parts store said my Cat. Converter could be getting clogged. Is that something that could cause it?

The egr should pull Exhaust gasses before the cat. I would assume something clogging the gas lines or your cooler leaking coolant into the EGR system.
Was there moisture in the valve when you pulled it?

I'm assuming that the truck seems to be running fine? If so it may be a matter of simply clearing that code now that you've made the repair. Disconnect the batteries and turn on the headlight switch....let it sit for 20 minutes or so then turn off the headlight switch and hook the batteries back up. If the problem is still there the code will return after a few engine warm up cycles.

The old valve was completely clogged at the top opening.

sounds like you are putting a bandaid on a gunshot wound. Are you by any chance an elected official?
I would find out what is getting into the system to clog it, and then replace the EGR valve. Chances are the EGR is only the aftermath of the true problem

Clogging may be normal in some operating environments that include high mileage, extended idling, and insufficient high speed / power running.
Make a habit of doing Italian tuneups once a week.
Also --- there may be a lot of trapped carbon in the intake that have to be blown out --- unless you want to spend the $$$ to clean it out manually.

I think we can rule out the cat as the problem. I hate to disagree with an auto parts store guy, but I think I will.

As badly caked as you described the EGR valve to be, I wonder if the IAT2 sensor is gunked up enough to where it's not reading the air temp properly, and the pcm thinks there's not enough EGR?
Maybe one of the techs can help out with that one.

Where is the sensor located at? I'll have to check it out.
