89 S15 Jimmy EGR Problem
89 GMC S15 Jimmy 4.3 TBI Auto Trans.
So for 2 days i have been chasing down a problem with the Jimmy's idle surging and dying. After checking and replacing just about every vacuum line. I found that the EGR was not getting enough vacuum. I tracked it down to this little thing.

What in the world is it? It connects between the EGR and the vacuum port on the TBI.
I disconnected the EGR from it and manually gave it vacuum and the Jimmy idle perfectly. I reconnected it to where it belongs and it just died.
My question is.... What is it? Can it be bypassed?
Any help would be appreciated.
