Well, got the egr out, cleaned it up and verified all passages are clear, and had a nightmare getting it back in but it is in. Still no love when applying vacuum. I am sure the diaphragm inside opens up - throttle body cleaner flowed freely between when I applied vacuum.
Next step, exhaust baffle.
I am not quite ready to say the 261 causes a lean condition. I need to get the egr system running and then see how emissions is doing.
Am considering getting a wide band o2 so I can really know what is happening.
Back to wrenching!
