I thought mine was running fine with the EGR but it turns out one of the rubber fittings at the thermo-vac switch on the t-stat housing was torn so there's no telling how long its been disabled. I was planning on dealing with it later. I'm going to eventually do away with all of the extra vac lines and such so unless its stuck open I guess its inoperable right now. Runs great.
