Fixkick,
I think i've solved the idle issue with a new EGR main valve. I blew in the large tube while covering the main hole and sensor hole and I could hear some air leaking out the old valves port. I think that was the problem. An incomplete seal. If I knew more about EGR's and paid attention to your documentation, I could have diagnosed the old one after I cleaned it. I'm learning.
I'm curious if the large tube hose going to the egr valve should have a hose clamp on it? On my vehicle, there was no hose clamp and I'm wondering if the large air hose to the EGR valve can cause idle issues? It didn't have an enormously tight seal.
I'm glad to have this one solved. Will drive it some more, but it seems fixed. I had to screw in the fuel air a couple of turns to bring down the idle now that there was no further air leak.
