Holy plugged passages batman! These are the fabled 3 EGR passages that lead directly to the EGR valve, and obviously mine were completely plugged up. In fact it was so plugged up that I didn't even recognize the passages until I sprayed some Berrymans into the EGR passage behind the EGR valve itself & it started to ooze out the middle TB passage (the other two were 100% blocked.) And I also wouldn't have found all this buildup if I hadn't carefully removed the TB gasket.
All I can say about your message is
AWESOME.
I also took off my TB this past weekend, but could not find the elusive EGR passage that everyone was talking about. If it weren't for your message, I would probably be replacing the EGR pipe in the near future.
Here is a picture of the UIM behind the TB on my car:

I thought that those three areas at the front of the UIM opening were just indentations in the aluminum cast!
I can't tell you how thankful I am that you wrote your message. If I could figure out how to give you 5 stars I would.
