Re: Another EGR valve question...(More info) assumptions based upon my test mentioned above are not enough to consider the valve bad. I stopped by NAPA this morning and a brand new EGR valve had the same behaviour...holding a finger tightly over the vacuum inlet of the valve seemed to make no difference in the resistance of pushing the diaphragm.

I have watched for movement of the valve on the vehicle and there is none, that's why I originally thought the valve was bad. I picked up a hand vacuum pump today, so I will try applying some vacuum to it tonight and see if it moves.

I may just go in for the test with the EGR vavle as it is...might just pass with my recent re-jetting of the carb.

Thanks for all the help and suggestions.
