I deleted some of my past larger attachements !

Back to something you POSTed earlier... where you said:

"Get rid of all the lines to and from the black box on the valve cover."

Do you mean this literally?... if you are you speaking of what is often called the 3-in-1 vacuum valve? Well on both my 240D and 300D MBZs I have concluded this vacuum valve not only switches the EGR on/off but also turns on/off the "bleed" effect of the VCV on the IP. I'm not certain but I think this has something to do with preventing the tranny from prematurely down shifting when you let off the accelerator.

I have to go now but will be back later on this IMPORTANT subject.
