Another EGR valve question...(more info)
I was attempting to "test" my EGR valve today before I go in for another emissions test.
How much vacuum should it need to pull the valve open? I could push the diaphram open by hand, but i couldn't get any ported vacuum to have enough force to open it. It did take a bit of pressure to push it open by hand too.
Is this a sign of a bad EGR valve?
I bypassed the CTO valve for the test and hooked a vacuum line directly to the EGR, and could feel that there was a vacuum present, it just didn't seem to have enough vacuum, to pull the valve open.
I don't have a vacuum guage, so i don't have any real numbers to post.
