Complete delete of all the vacuum lines and vsv,evap, fuel switch valve, made block off plate for the egr, but couldn't find a plug for the pipe and didn't want to pull lower manifold to go after it yet. Will wait till I have the head off. Also cleaned manifold and throttle bottle. So now I'm running no pair, put o2s in there place, no egr no vsv no vacuum lines other then the fuel pressure regulator. Idles nice and smooth and can fit my whole arm into the gap of the manifolds
