DOH!, thanks for the info. It would be nice though if the authors of their own threads would modify their subject from "OMG I NEED HELP HERES PICS" to "Problem fixed, how to clean EGR". Or mayby im just being a whiny B****, in which case im sorry. But thanks for the info.
Dead wrong. The digital EGR valves are VERY expensive, and it'* POINTLESS to buy one when you can clean it with great results nearly every time. I've seen DOZENS respond to cleaning, and can't think of a single one that'* actually failed on this Forum.

The Linear EGR used from 94 and newer is a different story, but that'* not what we're talking about here.

Well from experience, mine failed 3 times going through emissions here in Maryland, Cleaned it out 3 times and finally after the getting a brand new one from GM, it passed emissions. So from experience, I Know and I won't let anyone tell me any different.

But it wasn't throwing a code, was it? Yours was packed with crud, something we've never seen before. The cleaning we're talking about here is for when it throws a code for a solonoid that should have opened and couldn't.

You have one of TWO digital EGR'* I've ever heard about that had to be replaced after cleaning. If you look at the numbers, Digital EGR'* respond well to cleaning about 95% of the time. You just had a lemon.

Maybe so, but when I did clean it, the first time it was spotless and 2nd and 3rd. There was no crud on them but the normal carbon you would see from an EGR. My car only has 120,000 miles on it and is always being well taken care of. So Maybe the EGR valve was a lemon but it does show they do fail and they are man made. An Ole saying if its in a car and it heats up it will fail sometime or another.
