EGR valve?

Coming home from work today SES light comes on, on my '98 Olds Bravada 4.3L.
Ran scan tool. Got code:
P0404-Exhaust Gas Recirculation Control Circuit Range/Performance.
Does this mean I have a bad EGR valve?
I only have driven about 10 miles since the light came on and noticed no driveability issues. I had noticed on this last tank of gas that I was getting poor mileage. Blamed it on the cold -20 here....brrrrrr.
Anyways, I have 127000 miles on it and would appreciate any help.
Thanks

Yes, it's likely carboned up and not seating properly. Sometimes they can be cleaned but I generally replace them to avoid future problems.

A piece of carbon may have been stuck in the egr valve.Tomco makes a gasket with a screen which will keep the carbon out.They don't last forever though.Yes your pic is the egr valve.Remove the valve clean it with carb cleaner and reinstall with the above mentioned gasket.Start the engine and rev it a couple times before bolting th egr back on.Try to remove the egr with the engine cold so the intake doesn't strip out.

When you remove it there will be 2 ports on the bottom, 1 of them has a pintle in it. You should be able to push it open and clean all the carbon with carbuerater cleaner. Finish off with some WD 40. Even if this works, it will likely be only temporary. Other things get worn and sticky inside too. A new one is the best way to go. $200 isn't bad because it is 3 stage, all electric instead of vacuum. I've seen them as high as $400.

Thanks for the replies. I decided not to mess with it and just bought this one:

Now....should I still get a screen gasket and if so where can I get one? Do I need to order?

OOH, I never would have trusted that. There are MANY different part numbers for those things. I wouldn't have even trusted anything other than a Delco brand. Your being penny smart and dollar foolish and just asking for trouble. If you can get out of that sale, just go to an aftermarket supplier and order a Delco replacement. Would you trust your life to a heart pacemaker you bought on E-Bay?

From what I understand, that's what this is. I've done some research and this is the right part #.
I've had VERY good luck using Ebay. The majority of sellers are honest people and I guess it's a chance I'll have to take.

Comparing an auto part to a pacemaker is a little bit of a stretch.
I appreciate your concern though.

I've ended up with some real junk from those guys. With electronic components, quality is important. Diagnosis can't get pretty hard if you can't rely on your parts. E-Bay is not the place to buy that stuff. What are you going to do if you have a problem with that part?

I guess I'll cross that bridge when I get there.

Just wanted to update.

I received the part in 2 days and it was a genuine Delco part.
Replaced it in under 10 minutes, and saved a bundle.
Thanks for all the help.
