Hello,
I think I found issue. Last night I pulled the EGR valve off and cleaned it out. It did not appear to be sticking and did not leak but I could see the Gasket was not in the best shape. I cleaned it all up and put it back on using sealant and fixed the stripped bolt.
I then used a spray rubber sealant and spayed all of the vaccume hoses and all around the Intake Manifold gasket and let it dry overnight. This morning the car purred like a kitten and even better the engine did not surge or shake at idle anymore. Beautiful!
As I drove to work I was reading the Fuel Trims and the Short Term FT was back and fourth between 5% LEAN (-) and would sometimes swing up but no higher than 15% and that was rare. The Long Term FT averaged around 14%.
At Idle the Fuel Trim averaged around 12% but no higher. This is much improvment than before!
You were definantly right about the vaccum leak!
