I managed to pass the emissions test finally .......... the initial analysis turned out to be bogus from my non-MB mechanic. I managed to get hooked up with a couple of dudes that run an MB shop. They obviously figured out that my EHA had been disconnected ............... so they re-hooked it up, ran it through some tests and voila passed with flying colors. They also changed my plugs since leaking oil got to them.

That seem to get rid of my high idle problems as well.
